I started with a ship full of max-level veterans, and I'm just a complete noob.

Vasily entered the Fifth Academy's main hall with three technical deputies, carrying a supplementary instruction file stamped with a red clay seal. A translator followed closely behind, handing the temporary summons request to the duty officer.

He repeatedly urged in Russian that the Chinese side immediately convene all key technical personnel and sign a parameter freeze agreement before the general meeting.

Upon seeing the Soviet Technical Committee's seal on the supplementary file, the duty officer immediately dialed 502 and urged Jiang Ming to bring the materials to the Fifth Academy.

At this moment, Jiang Ming was still sitting next to the telephone in the 502 confidential cubicle, with a waterproof sealed bag next to him, and the other end of the receiver was the semiconductor laboratory of the Institute of Physics.

Wang Shouwu is reading out the high-frequency data of the second round of diffusion samples. The modified flow feedforward has completed its first round of calibration, and the junction capacitance dispersion has begun to decrease, but the passband edge still has obvious fluctuations.

"Sample No. 6 attenuated prematurely at the high-frequency end, the surface leakage was normal, and the cross-section showed that the base region was one stop wider than the target value."

Jiang Ming recorded the data on the device process card and checked the oxidation, windowing, and annealing times according to the diffusion rules of silicon tubes.

The current batch of devices is tasked with continuing to approach the 800 MHz threshold. The previous 341 MHz only proved that the route was valid. To truly support short frame reception, a narrower base region and a smaller junction capacitance are still needed.

"Shorten the annealing time, do not change the main diffusion temperature, first widen the base region and push it back, leave the calibration film in its original position, and record the flow rate switching separately."

On the other end of the phone, Da Liu repeated the parameters. After Wang Shouwu checked them, he asked the operator to adjust the timing cam.

Jiang Ming then instructed Fang Xudong to retrieve three high-purity quartz substrates from the warehouse for the next step of packaging and parasitic capacitance comparison.

"Only three pieces left. Two people must sign for them when they are shipped out. First, the surface must be cleaned and the size must be checked. If even one piece is broken, we have to stop shipping."

Fang Xudong left with the transfer order, and the liaison officer sent by the Fifth Academy arrived at the same time. As soon as he opened the door, he heard about the base width, junction capacitance and quartz substrate, and his impatience immediately appeared on his face.

"Engineer Jiang, Comrade Vasily has arrived at the Fifth Academy and is waiting in Conference Room No. 1 to sign the parameter approval document. Are you still talking about these small parts?"

Jiang Ming covered the receiver and looked up at him.

"Axel needs to distinguish short codes; the passband and group delay of the receiving preamplifier all fall on these components. I'll go over there after the call ends."

The staff officer walked to the table and reached for the telephone switch.

"The diplomatic setting is already in place; the device parameters can be handed over to the subordinates."

Old Sun came in from the outer room, carrying a large wrench he had just removed, and stood directly between the staff officer and the telephone.

"The people downstairs are guarding a furnace of silicon wafers. If you touch the phone, the annealing time will be cut in half. Who will sign off on the defective products?"

The staff officer looked at the wrench, then at the calculation bag on the table covered with a Class A seal, and could only pull his hand back and turn to the corridor to urge the car to leave.

Jiang Ming listened to Wang Shouwu finish reporting the last two sets of data, and based on the changes in passband flatness, he adjusted the annealing correction range to be within the allowable range of the process.

"First, do two control samples, and then decide on the parameters for the whole batch after the capacitance bridge is tested. Don't sacrifice the integrity of the oxide layer just to meet the 800 MHz requirement."

Wang Shouwu accepted the arrangement. As soon as the internal line was finished, an abnormal noise came from the backup diesel generator in the backyard of the factory. The speed dropped continuously and the exhaust sound became intermittent.

The corridor ceiling light dimmed several times, and the voltage regulator in the confidential compartment began to emit a low hum. Old Sun picked up his toolbox and headed towards the generator room.

Jiang Ming put away the phone records and followed them to the backyard. The diesel engine was almost shut down, and the mechanic on duty was repeatedly turning the fuel supply lever.

Old Sun reached out and touched the high-pressure oil pipe, then unscrewed the drain plug at the bottom of the oil filter. The diesel fuel that flowed out contained fine gray-black residue.

"Don't try to start the fire again, remove the filter first."

He removed the end cap of the oil filter and pulled out the metal filter screen. The mesh was mostly blocked by a layer of sticky impurities, and only the edge of the filter screen was left for diesel to pass through.

Old Sun put the filter screen into the cleaning tray, rinsed away the blockage with clean diesel oil, and then blew it through with compressed air in the opposite direction. His movements were so skilled that the mechanic next to him could only follow along and hand him tools.

Two minutes later, the filter was reinstalled, the hand pump purged the air, the diesel engine was reignited, the roar gradually returned to a uniform sound, and the voltage pointer on the voltage regulator returned to the working range.

Jiang Ming used tweezers to pick up the impurities in the cleaning pan. The black residue contained fibers, fine sand, and a layer of oil-sticky powder, which was different from the sediment in ordinary oil tanks.

When will this batch of diesel fuel be stored?

The mechanic on duty opened the handover form and pointed to the refueling record from that morning.

"The oil drums were delivered by the logistics and maintenance team. They were sealed intact, and the filter screen was cleaned just last night."

Old Sun put the remaining impurities into a sample bag, sealed the oil filter and oil drum, and asked the security department to verify them one by one with the logistics and maintenance personnel.

Jiang Ming looked at the layer of sticky powder. The diffusion furnace compensation line, the Fifth Academy communication branch, and the plant's backup oil line were all interfered with one after another. The other party's tentacles had already reached into the very last maintenance link.

This type of disruption does not require mastering the core formulas; simply stopping the equipment at critical junctures is enough to slow down parameter verification and device delivery.

Comrade Song delivered the latest report from Aksai from the military line office. The 24 GHz noise in the peripheral areas continued to intensify, and the short frame decision window had been compressed. Lu Qinghe requested that more stable pre-amplifiers be provided as soon as possible.

Jiang Ming put the report together with the silicon tube process card and checked the current progress of the two.

The guidance reverse calculation has formed complete physical evidence, the handwritten draft has been packaged, and the flow feedforward and annealing correction of the device group have entered the photo stage. The yield is still within a safe range that can continue to be promoted.

"The backup generator was changed to a two-person refueling system, and oil drums were sampled and sealed before being put into storage. During the high-temperature stage of silicon wafer production, the security department guarded the power supply room."

He signed the temporary security order, and Lao Sun and Comrade Song followed suit. The logistics and maintenance personnel's free access was immediately revoked.

When Da Liu returned from the workshop, he had two freshly roasted sweet potatoes in his arms, their golden-brown skins still steaming.

"These were taken from the stove in the cafeteria. Nobody's really eating properly today, so let's share them."

He broke the sweet potato in half and handed it to Jiang Ming and Lao Sun. The group sat around the enamel mug and drank water. The sweet aroma temporarily masked the smell of diesel and solder.

Old Sun took a bite, still thinking about the replacement cycle of Furnace No. 3, and mumbled a reminder to Fang Xudong to check the alumina furnace tubes tomorrow morning.

Da Liu then produced the capacitor data that Wang Shouwu had just sent, pointing out that the high-frequency fluctuations of the two control samples had been reduced, and the direction of annealing correction could be further verified.

After finishing the half-eaten sweet potato in his hand, Jiang Ming put the device card into a file bag, confirming that both lines had accumulated enough leverage to enter the next round of review.

In the main hall of the Fifth Academy, Vasily was still urging the translator to finish the translation. Three technical deputies had already spread the supplementary explanation files on the long table, and the consent forms were arranged in order of the names of the Chinese responsible persons.

He believed that the project milestones and the Soviet technical committee's seal were sufficient to push for a freeze, but there was no corresponding preparation in the supplementary dossier for the three sets of reverse tracks completed by the Chinese side overnight.

The telephone in the secure compartment 502 rang again, its sound carrying through the corridor where power had just been restored, drowning out the steady roar of the diesel engine.

Jiang Ming answered the receiver, and Qian Xuesen's assistant only said one sentence.

"Bring the Soviet three versions of parameters, the original Jiuquan radiosonde records, and all handwritten derivations, and immediately enter Conference Room One."
