"Miniature electron accelerator" capable of generating high energy electron beam with AA batteries

The National Institute of Advanced Industrial Science and Technology, "National Institute of Advanced Industrial Science and Technology", can accelerate electron beams to generate high-energy electron beams of 100 thousand electron volts or moreMicro electron acceleratorIt seems he has developed " Moreover, this microelectronic accelerator operates with an AA battery, it is small enough to fit in a small case, and it is easy to carry.

When we hear "to accelerate the electron beam to generate a high-energy electron beam", one scene of robot animation that shoots a beam and sniper the enemy by all means crawls over the head, but what exactly is it?

Details are as follows.
AIST: Development of microelectronic accelerator which operates with press release battery

According to this release, the "microelectronic accelerator" developed by the National Institute of Advanced Industrial Science and Technology, operated with 10 to 12 AA batteries as a power source, accelerates the electron beam using high frequency (microwave) It is said that it can generate high energy electron beams and X-rays of 100,000 electron volts or more for over 1 hour. Since it is possible to take one X-ray transmission image with X-ray within 1 to 10 minutes, it seems to be expected for portable X-ray nondestructive inspection to be used at work sites.

The length of the accelerator main body is about 20 cm, the weight is about 1.5 kg, and it is possible to carry it in a small case.

This is the main body. It is fairly small.


I tried to actually transmit peripheral devices of PC with X-ray.
