Energy particles detectors help astronauts out of the cabin →

At present, the questioning compartment of the Tianshi has been running for nearly a month at the track, and the Shenzhou No. 14 multiplication group has also invested in the preparation and preparation of the first out of the space station construction stage.

The top priority of the outlet activities is to ensure the safety of the astronauts under the high radiation environment outside the cabin. The time window of the outlet is one of the factors that need to be considered. Ask heavenly science popularization to continue to take you to understand the energy particles detectors that can help astronauts choose the time of outlet activities.

Energy particle detection is very important

Graval radiation is one of the important threats facing spacecraft and astronauts in human space activities, and it is also an important cause of material degeneration and biological mutation. Graval radiation detection is of great significance for how humans will safely get out of the earth, how to transform new materials, how to avoid mutation, and how to obtain new species. The accurate measurement of the type, energy spectrum, and flux of particle radiation is the unremitting pursuit of particle radiation detection scientists.

Energy particle detector ↑↑↑

Ask the energy particles on the experimental cabin mainly used to measure the energy, direction, and flux of the energy, direction, and general volume of various particles (high -energy protons, electronics, heavy ions and neutron) in the space station track ( The amount of particle) and the energy -pass density (LET spectrum) and radiation dose (radiation amount) of the energy of the transmission of them are available, so as to provide key reference data for space station safety, spaceholders' outlets, space materials, and biological experiments.

Four detection modules each show their magical powers

Ask the energy particle detector on the sky cabin is the first internationally of the first grain species with the most particle species and the most fulfillable scope of energy spectrum. It has 4 detection modules. It can use different principles to achieve multiple particle types and wide energy spectrum coverage separately. Essence

In the comprehensive detection module, scientists cleverly use the difference between the response of a single particle and different materials to design three different materials sensors, and to distinguish the energy and types of particles through logical arrangement and combination.

In the neutron module, as the first sensor made by using the new CS2LiyCl6: CE (CLYC) flashing body material, it effectively solves the problem of low neutron measurement efficiency.

In China Energy Electronics and Zhongye Proton Measurement Modules, it uses small holes imaging methods to lay 9 sets of silicon detectors behind the precision design of small holes to distinguish the direction of electron or proton incident in 9 directions in total, and and separate the direction of 180 °. Use electronics and protons and silicon reaction signals to measure the correlation with incident energy to measure incident electronics and proton energy.

It is of great significance to spatial environment research

Used for spacemen's outlet window forecast

Graval radiation is one of the major threats facing spacemen's outlets. The accurate amount of particle radiation time and space distribution measurement is used to provide accurate first -hand data for the spacemen's outlet window.

Used for space station in rail safety management

Graval radiation is also an important threat to the rails. Statistics at home and abroad show that human spacecraft account for more than 40%of the abnormalities induced by particle radiation. The accurate amount of particle radiation detection is a key parameter of the space station on the rail management risk aversion, the recovery of the failure of the failure of the failure, and the life of the key component assessment.

Provide key parameters for new materials and life experiments

One of the important mission of the space station is to provide a platform for new materials experiments and life experiments. It is a test site for human development of new materials, adaptability to the earth's environment, and transforming new species. Graval radiation is one of the most important environmental elements in the difference between outer space and ground. The accurate amount of particle detection will provide key research parameters for new progress of new materials and life experiments.

Used to discover major cutting -edge scientific issues

One of the key scientific issues of the Japanese and ground space weather has always been controversial. Returning to the decline of neutron is one of the important theories, but it has always lacked direct observation evidence. This survey will cover the detection of high-energy particles-atmosphere-neutron-electronic full chain, try to explore and crack this scientific puzzle.

In the future, the energy particle detector of the test compartment will be extended to the off -cabin exposure platform, which will continue to escort the operation of my country's space station. With its help, we will also witness more shocking out of the cabin.

I wish the Shenzhou 14th multiplier group

The first out of the cabin is successful and smooth
