I Have a Research Support System

"By the way, Xu Qiu, you have to register an account on the official website of Modu Light Source and take the 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 Modu Light Source on the 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 Modu Light Source includes:

A. Linear accelerator B. Intensifier C. Storage ring and beamline station D. Power cabinet

Each option is preceded by a box that can be checked.

Seeing the topic, Xu Qiu was stunned, how could he know this.

There is a box in front of the option, which usually represents an indefinite multiple-choice question, and a circle in front of the single-choice question.

Although D can be basically ruled out by the method of elimination, and the answer may be ABC, he still has no idea.

I had no choice but to ask Chen Wanqiu for help.

"Sister, how do you do this security test?"

"Search for the answer online, you should be able to find it," Chen Wanqing said, "You must answer all the answers correctly to pass the exam, but if you fail the exam, you can retake the exam.

Xu Qiu used Qiandu to search for "Madou Light Source Safety Exam Answers", and the first result he got was the exam answer.

The answer to the first question is indeed ABC. It seems that my deduction is quite reliable.

He went through the answers as a whole, and there were a total of 23 multiple-choice questions.

Then fill them in one by one, while also trying to remember the questions.

Be prepared, and use it in case of an emergency.

Finally, Xu Qiu double-checked the answer and clicked Submit.

The page shows that the security test has passed.

"Senior sister, I'm done answering," Xu Qiu said, "The answers to these test questions are already available online, is there still a need for the test?"

"It is better to have an exam than no exam, and you can always remember part of the content after answering the questions once.

In fact, the main reason is that the experimental operation is not very dangerous. If it is a high-risk experiment, the training will be much stricter.

By the way, take a picture of your user ID, it will be used later. "Chen Wanqing said.

…………

July 25, 7:30 p.m., laboratory.

"Xu Qiu, are the samples ready?" Chen Wanqing asked.

"I packed them in garbage bags. In addition, 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.

"It's well prepared," Chen Wanqing said, "Then let's go to the Family Mart convenience store and buy something to eat, otherwise we might be hungry in the middle of the night."

The two went to buy some biscuits, yogurt, and drinks, and then called an online express train to the synchrotron radiation light source in Zhangjiang New District, the magic capital.

After getting in the car, both of them sat in the back row.

Chen Wanqing squinted her eyes and closed her eyes, and Xu Qiu followed her example, leaning on the back cushion and closing her eyes.

It's a tough battle tonight, so keep your spirits up.

...

"Wake up, we're here."

Xu Qiu slowly opened his eyes, unexpectedly he fell asleep.

He raised his hand to look, confirmed that the samples and tools were still in the garbage bag in his hand, and followed the senior sister out of the car.

The garbage bags used in the laboratory are white and transparent and of good quality, so they are often used to hold 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, and we are here to do the test." Chen Wanqing said.

"Okay, come in and do the visitor registration."

Chen Wanqing entered the guard room and motioned Xu Qiu to follow.

The two filled in the name, ID number, contact information, unit, entry time and other information.

The guard brought two access control cards and handed them to the two respectively.

After receiving the access control card, Chen Wanqing walked to the self-service machine next to her, entered Teacher Wei's name, and found the machine time information assigned to them by the light source.

Then enter her and Xu Qiu's user numbers and set them as the users of the light source machine this time.

After the setting was successful, the self-service machine spit out two things the size of a USB flash drive.

"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.

After taking the personal radiation dosimeter and access card, the two left the guard room.

"There are so many procedures here." Xu Qiu said with emotion.

"Yes, after all, the Metropolis Synchrotron Radiation Light Source is a large project with an investment of more than one billion," Chen Wanqing said:

"The process is really cumbersome. First, after the light source is allocated, an email is usually sent to remind the user more than a month in advance;

Then the user submits information to the light source, including the number and type of samples to be tested, whether they are toxic, whether there are other special needs, whether the applicant has tested himself, etc. This step is also called a safety review;

The light source user office will generally review within five working days, and only after the review is passed can the information on the allocated machine hours be found at the self-service machine in the guard room;

The user comes to test at the designated time, registers at the guard, enters the light source, finds the corresponding line station, and then can test. "

It was already past eight o'clock in the evening, and it was completely dark, and there were street lamps on both sides of the road to provide illumination.

Chen Wanqing had been here twice before, so he led Xu Qiu to the main entrance of the testing center with his familiarity.

The two swiped the access control card to enter the interior.

The room is much cooler than the outside, and the central air conditioner is continuously working.

Xu Qiu looked around, and preliminarily deduced that this place should be a circular building, and the top of the building is very high, estimated to be more than ten meters.

Suddenly, there was an alarm sound in the distance.

"Sister, what's the voice?" Xu Qiu asked.

"This is normal, don't worry," Chen Wanqing said:

"Because the test cabin here is very large, the researchers have to go in and operate it. In order to prevent anyone from being locked into the test cabin, there will be an alarm before closing the door."

"Well, I thought something was wrong." Xu Qiu felt relieved.

"The place we are testing is 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 lounge, but simple partitions made of aluminum alloy and glass, so that the internal situation can be clearly seen from the outside.

On the outside of the test cabin, there is a striking warning sign "Beware of Ionizing Radiation", which is about the size of a container with a large door, 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 the computer, and it seems that it is still testing.

When he saw Xu Qiu and the two coming over with samples, he said hello:

"You guys are here, wait a moment, I'll test it right away."

"Okay." Chen Wanqing said.

Then, she dragged Xu Qiu to the next lounge.
