Background
The scintillation method is one of important methods for diagnosing the nuclear fission and nuclear fusion reaction processes, and is an important means for detecting neutrons, gamma rays and the like released in the nuclear reaction process. The device adopted by the scintillation method has a two-stage amplification structure, so that the device has high sensitivity, nanosecond time resolution capability and strong detection statistics, and in addition, because the scintillator can be processed to be very large and the radiation-light conversion process can be powered on, the device has strong advantages in rare event detection such as mesoparticle detection and cosmic ray detection.
The existing pulse radiation detection device usually adopts the traditional scintillators such as organic scintillators, plastic scintillators and the like, and forms a detection assembly with a photomultiplier tube (PMT) or a Photoelectric Tube (PT), and the detection assembly has the following defects:

2. the maximum linear current of a photomultiplier and a photoelectric tube serving as a photoelectric conversion device is generally about 200mA and even lower, and when the photoelectric conversion device is used, the sensitivity of a detection assembly needs to be carefully designed according to factors such as the intensity of a radiation field at the position of the detection assembly and the like, so that the working output current of the detection assembly does not exceed the maximum linear current of the photoelectric conversion device, the information such as the intensity of the radiation field can be accurately obtained, and the problem of exceeding the maximum linear output often occurs when the intensity of a radiation source is unstable;
3. because the photomultiplier and the photoelectric tube have high working bias voltage, generally 800-.
In addition, in recent years, the calcium-titanium-rich ore scintillator has higher atomic number, is used for X-ray detection in medical human body imaging, has higher sensitivity, can obtain clear X-ray imaging, and is expected to obviously reduce the irradiation dose of a human body, so certain advantages are shown in X-ray detection. However, no report on the use of such scintillators in pulsed radiation detection, such as pulsed neutron detection, is available at present.
