The accelerator in T County Hospital is old, and it has had all the problems that the accelerator will have in this life, and all the engineers of the accelerator factory have also come to treat it.

"People are born, old, sick and die, and so is the machine, and now it has reached the time when the oil runs out and the lamp is dry, but it has to continue to survive. Guo Gong shook his head and sighed while accompanying Volin around the accelerator room.

"And what's the problem now?" Warleen wondered.

"There is everything, the hand control box that controls the bed is not in good contact, the bed cannot be lifted or lowered, the head of the machine does not turn, and it is impossible to find out where the problem is; the rack rattles when it turns, and the motor and chain are worn out badly; these problems are okay to say, the most critical problem is that the dose rate is unstable, just like a person's heartbeat is unstable, the heartbeat is unstable and it stops beating, which is fatal. ”

Guo Gong was gesturing with his hands and feet while talking, and she was confused when she heard it, she followed Chen Xinyu in the accelerator factory to learn the debugging of electronic components, and she had never seen the problems that Guo Gong said.

Seeing that Volin looked confused, Guo Gong laughed: "Forget it, I won't tell you first, you follow first, and you will understand slowly." ”

"The electronic linear accelerator used in the hospital is a finished product after assembly, and the problem with the accelerator is that the components are damaged after debugging before assembly, which is still different from learning to debug parts in the manufacturer.

"For example, the debugging of the accelerator in the manufacturer, just like the programming of a computer programmer, after the accelerator is sold to the hospital, it is the customer's application of the computer, and if the computer has a problem, the customer only needs to repair or replace the problematic parts. ”

"In other words, is the difference between software and hardware?" concludes Wallen.

"It can be said that people who use computers do not necessarily have to know the specific programming of computer software. ”

Warlene wondered, "According to what you say, wouldn't it be useless for me to learn debugging from them now?"

"You can't say that," Guo Gong shook his head, "Wouldn't it be more handy for people who know software programming to use computers?"

"That's right. Wallen admitted.

She learned programming from Xiucai, and her confidence in using the computer has increased greatly.

However, she knew in her heart that even if she followed Chen Xinyu through the entire debugging process, she only knew that there was such a thing, and she wanted to master all the debugging skills, unless she was really transferred to work in the accelerator factory.

Warlene and Guo Gong were chatting in the computer room, Shi Huijie, Chen Xinyu, Xiao Sun and Wang Gong were studying ways to solve the instability of the dose rate in the control room.

In the end, Shi Huijie made a decision: "Let's go through the program again and see if there is anything neglected in the details." ”

"Done. Just do it, Xiao Sun put the oscilloscope on the rack, Chen Xinyu debugged the dose rate, and Shi Huijie paid attention to the overall situation.

Time passed slowly, the sky had turned dark, and the dose rate was still unstable.

Shi Huijie asked Chen Xinyu and Xiao Sun to stop: "It seems that this method will not work, you have to squat in the computer room, Guo Gong, you come in with me." ”

Volin didn't understand: "Senior Brother Chen, what do you mean by squatting in the computer room?"

Chen Xinyu didn't explain: "You'll know later." ”

"Okay. Guo Gong agreed, opened the bulky protective door in the computer room, and he and Shi Huijie walked in.

Chen Xinyu closed the protective door and pointed to the TV used as a monitor for Warlene to see.

Warlene saw that after Shi Huijie and Guo Gong operated on the head of the accelerator, the two of them squatted side by side under the wall of the computer room, facing the accelerator, and their eyes were also staring at the accelerator, the two didn't know what to say, and then Shi Huijie shouted: "Turn off the lights." ”

Chen Xinyu pressed the light switch on the wall, the lights in the computer room, and Wo Lin couldn't see anything on the TV except for the snowflakes.

"You turn it on. Chen Xinyu instructed Waren.

"Good. Warlene didn't hesitate.

The boot procedure is very simple, first enter the dose to be out of the beam (out of the radiation) on the monitor, open the key switch on the console, press the beam button, Warlene has watched Guo Gong operate for an afternoon.

With the press of the unbundle button, Wallen heard the sound of "Bang Bang Bang" coming from the TV, intermittently and irregularly.

Under the command of Shi Huijie, Warlene repeatedly turned on and stopped, she heard the sound of "help help help" sometimes when the machine was turned on, sometimes it didn't, sometimes the sound lasted for a long time, sometimes it lasted for a short time, Wallen didn't understand what was going on, and she didn't ask.

Because Chen Xinyu and Xiao Sun were staring intently at the oscilloscope, she was afraid of disturbing them.

In addition to turning on and stopping the machine, she also keeps an eye on the monitor.

I heard Shi Huijie shouting: "Turn on the lights." ”

Warlene hurriedly pressed the light switch on the wall, she didn't see Shi Huijie and Guo Gong from the monitor, but she could hear Shi Huijie shouting to open the door, Shi Huijie and Guo Gong should have withdrawn to the protective maze.

The protective door opened, and Shi Huijie and Guo Gong immediately rushed out of the door.

As soon as Shi Huijie came out, he asked Wang Gong: "Did you bring an iron piece?"

"I must have brought it. Wang Gong spoke, picked up his toolkit and walked to the computer room.

Then everyone else followed him in, and Wallen was no exception.

Entering the computer room, Shi Huijie pointed to a part of the accelerator and told Wang Gong: "There is fire here." ”

Guo Gong told Warlene: "This is the magnetron, and I and the construction saw the ignition of this part of the magnetron, which should be the ignition of the magnetron wall caused by the deflection of the magnetic field track." ”

Warlene nodded, saw Wang Gong take out an iron piece and asked, "Where?"

"Here. Schwig pointed to the specific location of a magnetron.

Wang Gong's iron piece was not pasted to the position pointed by Shi Huijie, but was pasted in another place.

Guo Gong explained to Warlene: "The purpose of attaching iron sheets is to adjust the magnetic field ......"

There are also several layers of iron in one place of the magnetron, and it seems that this is not the first time that the magnetron has had problems.

Wang Gong pasted a layer of iron sheets, Chen Xinyu measured the voltage of the automatic frequency stabilization system once, until Shi Huijie said "try", Wang Gong stopped pasting iron sheets, everyone out of the computer room, and repeatedly turned on the beam again.

Warleen was already hungry, but no one else said she wanted to eat, and she was too embarrassed to mention it.

The next time is to repeatedly paste the iron sheet and move the position of the iron sheet, repeatedly measure the voltage of the automatic frequency stabilization system, and repeatedly turn on and off the machine.

At about ten o'clock in the evening, Shi Huijie asked Volin, "Girl, are you hungry?"

Warlene smiled bitterly: "Master, are you hungry?"

"I'm not iron-clad, I'm already hungry!" Shi Huijie spewed out a swear word.

Although he was hungry, he didn't want to interrupt the commissioning of the machine, so he could only go hungry until he finished his work, which had been his habit for many years, and others were like him, not finishing their work and not eating, unless they were completely hopeless.

Guo Gong hurriedly asked: "Everyone, I have already ordered the meal, shall we eat here, or go to the store to eat?"

Shi Huijie waved his hand: "Let's eat here, hurry up and go home after work." ”

The automatic frequency stabilization system is basically normal, but I can't be sure that the dose rate will really return to normal, and I will continue to work after eating.

"Okay, I'm going to get the guy to deliver the food. Guo Gong strode out.

Shi Huijie asked Warlene: "Girl, do you know why we squatted in the computer room, and we were still squatting at the base of the wall?"
