Chapter 124: Novice person in charge

　　 Thursday morning at 7:30.
　　 Xu Qiu, Chen Wanqing, and Han Jiaying gathered in Caiyi 216, and then took a taxi to the Magic City synchrotron radiation source. The test item was grazing incidence X-ray diffraction GIWAXS.
　　The samples have been prepared in advance, this time there are a lot of samples, there are a full 108.
　　 The light source test is still quite troublesome. Regardless of the steps of applying for the machine in the early stage and safety review, the preparation of more than one hundred samples alone took them two days.
　　 brought samples, gloves and other experimental equipment, the three of them moved towards the school gate, Xu Qiu said casually:
　　 "There are 108 samples this time, the test pressure is relatively high, I don't know if they can all be tested."
　　 "Then give priority to testing you. Anyway, there is another chance to test this year." Chen Wanqing said:
　　 "I think your sample has good crystallinity, the GIWAXS result should be good, and the signal will be more obvious."
　　 "I hope, this is the last test." Xu Qiu said.
　　 "Brother, come on." Han Jiaying said.
　　 didn't wait long, the previously reserved car drove to the three of them and stopped slowly.
　　 The driver is a young man. Xu Qiu opened the door, sat in the front passenger, fastened his seat belts, and the two girls took their seats in the back row.
　　 Because it is in the front and rear seats, it is not convenient to chat, and not long after getting in the car, Han Jiaying narrowed her eyes.
　　 It seemed that she had just woke up not long, and she was still a little sleepy.
　　 Xu Qiu simply closed his eyes and entered the simulation laboratory.
　　 Since the liver exploded on Friday and Saturday two weeks ago, the efficiency of the P2FBT4T-2OD system rushed to more than 10% in one fell swoop, he did not enter the simulation laboratory to do experiments.
After 　　, various characterization tests were supplemented, including gel chromatography, nuclear magnetism, and transmission electron microscopy.
　　 Every time he takes a test, he will copy the relevant skills of the teacher in charge of the test, and at the same time move the corresponding laboratory into the simulation laboratory.
Most of the laboratories are relatively small. The volume of the 216 laboratory is no more than 100 cubic meters, and the volume of the simulation laboratory now has a space of 10,000 cubic meters. It is no problem to plug several laboratories of the same size. You can edit and delete them if you don't need them.
　　 Although these laboratories are useless for the time being, there is no guarantee they will be used in the future.
　　 However, a behemoth like the Moto synchrotron radiation light source, it is impossible to move it all in.
　　 After simply strolling around in the simulation laboratory, Xu Qiu stepped out and started to close his eyes and rest.
　　 He wants to save his energy, and he will have to fight with 108 heroes later.
　　……
　　 More than half an hour later, at the door of Modu's synchrotron radiation source.
　　 "Wow, this place is big." Han Jiaying exclaimed.
　　 "Yes, after all, it is one of the largest testing centers in China." Xu Qiu said.
　　 The last time he came, it was past eight o'clock in the evening, and it was still dark, and only a rough outline could be seen from the inside.
　　 This time I looked at it from the outside, and the look and feel was different. A giant eggshell-shaped building was really big.
　　 Chen Wanqing is not surprised, she has been here many times before.
　　 After she greeted the doorman familiarly, she first registered her personal information, then entered the information at the self-service terminal next to her, and took the radiation dosimeter.
　　 Xu Qiu and Han Jiaying also registered information, and then got the radiation dosimeter and access card.
　　 The three people entered the main entrance and found the BL14B1 line station.
　　 No one is testing at the station this time, and the instrument is empty.
　　 Next to the desk, there is a guy in his early twenties sitting in a swivel chair and brushing DY, unlike the teacher here.
　　 After hearing the movements of Xu Qiu and others, he put away his mobile phone, looked up at the three of them, paused for a moment on Han Jiaying’s face, and then said:
　　 "Are you the users who tested during the day today?"
　　 "Yeah." Chen Wanqing nodded.
　　 "My name is Meng Ren, it's like this." He paused and continued:
　　 "Today I was on duty with another teacher, but that teacher had something to do in the morning, and it might take more than ten o'clock to arrive.
　　 So if you are not in a hurry, you can wait for a while, because I just came here and the experiment operation is not too proficient. "
　　 Yes, when I met a novice, Xu Qiu muttered to himself.
　　 Magic City synchrotron radiation source is regarded as a research institute, similar to universities, it can also recruit master students, doctoral students and post-doctoral students.
　　 Mengren should be a graduate student of the new light source, who is a graduate student or a doctoral student, because he is afraid of breaking the instrument or other reasons, he dare not or do not want to use it.
　　It’s just that their test task is very tight today. If there is a delay of two or three hours, it is very likely that incomplete samples will be tested.
　　 Although he copied Teacher Luo Yang's Tier 5 skills, he has learned the relevant experimental operations, including debugging and cutting, but it is not easy to display it directly, after all, there is no way to explain the source.
　　 I still have to ask the little brother in front of me to help.
　　 "Brother Meng Ren, we have a lot of samples today. I'm afraid I won't be able to finish the test after a long delay..." Xu Qiu said:
　　 "Our samples are all nano-scale polymer films, and the substrate is the same batch of silicon wafers. It only needs to be cut once, which should not be very troublesome."
　　 "This..." Meng Ren appeared hesitant.
　　 Seeing this, Xu Qiu secretly poked Han Jiaying next to her with her hand.
　　 The school girl understood in seconds, and quickly replied: "Yes, please help us."
　　 "Let me try," Meng Ren agreed, and explained by the way:
　　 "I didn't mean to not help you, mainly because I was afraid of breaking the instrument."
　　 Get it done.
　　 As for breaking the instrument, there is no such thing.
　　 The software and equipment in the light source have their own protection program~EbookFREE.me~ Unless it is physically damaged, it is quite difficult to break it.
　　 Besides, Xu Qiu was watching by the side. If something really happened, he wouldn't just sit back and watch.
　　 He gave the school girl a thumbs up, and Han Jiaying also smiled at him knowingly.
　　 Chen Wanqing looked at them suspiciously, what are these two people doing secretly under her nose?
　　……
　　 Everyone came to the test chamber next to him, Xu Qiu began to teach Han Jiaying to place samples, search, open and close the door and other basic operations.
　　 After placing sample No. 1, close the door, turn on the light, and return to the office.
　　 Meng Ren sat in front of the computer, preparing to debug, while others were watching.
　　 It can be clearly seen that Meng Ren is a little nervous, and the mouse is not grasping securely.
　　 After opening the operating software, he checked the user manual while typing the code.
　　 First, adjust the vertical position of the sample stage to find the state when half of the X-ray hits the side of the sample.
　　 In theory, this step is not difficult, but Meng Ren soon encountered a problem:
　　 The signal strength of the detector varies from 0 to 3500.
　　 No matter how you adjust it, the highest value can't exceed 3500.
　　 Under normal circumstances, the highest signal strength should be around 30,000, which is an order of magnitude lower, which is obviously abnormal.
　　 What is the reason?
　　 Meng Ren scratched his head and entered a few strings of codes, but unfortunately it was still to no avail. He scratched his head helplessly again.
　　 Chen Wanqing and Han Jiaying couldn't understand, they looked at each other blankly.
　　 Xu Qiuze stood leisurely beside the back, waiting to be reminded.
　　 At this time, Meng Ren lay back and said:
　　 "I can't figure it out, but I should call and ask my tutor."
