I Have a Research Support System
Chapter 49: Light source test (on)
"By the way, Xu Qiu, you have to go to the official website of Magic Light Source to register an account and take a security test before you can go to the light source test. I almost forgot," Chen Wanqing said:
"Otherwise, there will be no information about you in the system, and you won't even be able to enter the door."
"Okay." Xu Qiu nodded and opened the website of Magic Light Source with his computer.
Click User Registration, fill in the information and submit, the page shows that the registration is successful.
Xu Qiu found the security exam interface.
The first question, the ray device of Magic Light Source includes:
A, linear accelerator B, intensifier C, storage ring and beam line station D, power cabinet
There is a box in front of each option, which can be checked.
Seeing the topic, Xu Qiu looked confused, how did he know this.
There is a box in front of the option, which usually represents indefinite multiple-choice questions, and multiple-choice questions are usually surrounded by a circle.
Although D can be basically eliminated through the elimination method, the answer may be ABC, but he still has no idea.
There is no way, so I have to ask Chen Wan for help.
"Senior sister, how do I get this safety test?"
"Search the Internet for the answer, you should find it," Chen Wanqing said: "You must get all the correct answers to pass the exam, but if you fail the exam, you can retake the exam.
Xu Qiu used thousands of degrees to search for "Medical Light Source Safety Test Answers", and the first result obtained was the test answer.
The answer to the first question is indeed ABC, it seems that my inference is quite reliable.
He turned over the answer as a whole, and there were 23 multiple-choice questions in total.
Then fill them in one by one, and try to remember these questions.
It is prepared, and it is used in case of emergencies.
Finally, Xu Qiu repeatedly confirmed the answer and clicked submit.
The page is displayed, and the safety test is passed.
"Senior sister, I have finished answering," Xu Qiu said: "This test question has answers on the Internet, is there any need for an exam?"
"An exam is better than no exam. You can remember part of the content after answering the questions once.
In fact, the main reason is that the experiment operation is not dangerous. If it is a high-risk experiment, the training will be much stricter.
By the way, take a photo of your user ID, you will use it later. "Chen Wanqing said.
…………
July 25, 7:30 in the evening, laboratory.
"Xu Qiu, are all the samples ready?" Chen Wanqing said.
"I packed them in a garbage bag, and I also brought two tweezers, a pack of disposable PE gloves, a few disposable latex gloves, and a few spare garbage bags." Xu Qiu said.
"You are well prepared," Chen Wanqing said: "Then we will wait for the family convenience store to buy something to eat, otherwise we may be hungry in the middle of the night."
The two went to buy some biscuits, yogurt, and drinks, and then called an online appointment express to go to the synchrotron radiation source in Zhangjiang New District, Magic City.
After getting in the car, they both sat in the back row.
Chen Wanqing squinted her eyes and closed her eyes to rest, and Xu Qiu also followed her, leaning on her back cushion and closing her eyes.
Tonight is a tough battle, we must cultivate our spirit.
……
"Wake up, I'm here."
Xu Qiu slowly opened his eyes, but he did not expect to fall asleep.
He raised his hand and looked at it, confirming that the samples and tools were still in the garbage bag in his hand, and then got out of the car with the senior sister.
The garbage bags used in the laboratory are white and transparent, and of good quality, so they are often used for samples and reagents.
The two arrived at the door of the light source and were stopped by the guard.
"What are you here for?"
"We are the users of the light source, to do the test." Chen Wanqing said.
"Okay, come in and do visitor registration."
Chen Wanqing advanced to the guard room and motioned for Xu Qiu to follow.
The two filled in information such as name, ID number, contact information, unit, entry time, etc.
The guard brought two access control cards and handed them to them respectively.
took the access card, Chen Wanqing walked to the self-service machine next to him, typed in Teacher Wei's name, and found the time information assigned to them by the light source.
Then input her and Xu Qiu's user numbers, and set them as the users of the light source.
After the setting is successful, the self-service machine spit out two USB flash drives.
"This is a personal radiation dosimeter. You need to carry it with you when you are inside the light source and return it here when you leave." Chen Wanqing said.
took the personal radiation dosimeter and the access card, and the two left the guard room.
"There are so many procedures here." Xu Qiu said with emotion.
"Yes, after all, the Magic City synchrotron radiation source is a large project that has invested more than one billion yuan," Chen Wanqing said:
"The process is really cumbersome. First of all, after the light source is allocated, usually an email is sent to remind users more than a month in advance;
Then the user submits information to the light source, including the number of samples to be tested, type, toxicity, other special requirements, whether the applicant himself tests, etc. This step is also called security review;
The light source user office will generally review within five working days. After the review is passed, the assigned time information can be found on the self-service machine in the guard room;
The user will test at the designated time, register at the guard, enter the light source, find the corresponding line station, and then test. "
It's now more than eight o'clock in the evening, it's completely dark, and there are street lights on both sides of the road to provide lighting.
Chen Wanqing had been to www.ltnovel.com twice before, so Xu Qiu, led by a light car familiar with the road, found the main entrance of the testing center.
The two swipe their access card to enter the interior.
The interior is much cooler than the outside, and the central air-conditioning is continuously working.
Xu Qiu looked around and preliminarily concluded that it should be a circular building, and the top of the building is very high, probably more than ten meters.
Suddenly, there was an alarm sound in the distance.
"Senior sister, what's your voice?" Xu Qiu said.
"This is normal, don't worry," Chen Wanqing said:
"Because the test chamber here is very large, the researchers have to walk in and operate. In order to prevent someone from being locked into the test chamber, there will be an alarm before closing the door."
"Well, I thought there was something wrong." Xu Qiu relaxed.
"The place we tested was at the BL14B1 line station. Go to the left." Chen Wanqing said.
Along the way, they passed many test line stations, most of which consisted of an office, a lounge and a test cabin.
There are no doors in the office and the lounge, but simple partitions are made of aluminum alloy and glass, and the internal situation can be clearly seen from the outside.
There is a striking warning sign "Beware of Ionizing Radiation" posted on the outside of the test cabin. It is about the size of a container and the door is large, about three meters wide and two meters high.
After walking about a few hundred meters, Xu Qiu finally saw the sign of the BL14B1 line station.
Someone inside is operating a computer, and it looks like it is still being tested.
When he saw Xu Qiu and two people coming with samples, he said hello:
"You are here, wait a moment, I will finish the test right away."
"Okay." Chen Wanqing said.
Then, she took Xu Qiu to the next lounge.
