Project summary

The RIPT vacuum devices pision was created about 30 years ago. Up to now the pision has developed several tens kinds of photocells, PMTs, image devices and X-ray intensifiers, X-ray and gamma detectors etc., which were the base of the nuclear charge test equipment. Devices were created with unique temporal resolution and output current linearity level.

Since in the latest period the test operations were suspended,the volume of works for the pision was considerable reduced. That is why the pision is ready to begin alternative developments of devices for High-Energy Physics and for Medicine using existing technological basis and equipment complex.

In the Project foresee the developing of three types of photoelectronic devices for High-Energy Physics: magnetic focusing optoelectronic delay line (~1ms) for selecting of 0,1% information signals, Magnetic Focusing Image Intensifiers and modernising PMTs for Highly Magnetic Environments.

Besides three types of specialised PMTs will be developing in the project for Medical Tomography: two channel types: 16-channel with external dimensions 24 x 24 mm and 4-channel with external Idleensions 40 x 40 mm for Position-Emission Tomography (PET) and rectangular with dimensions of photocathode 10 x 50 mm - for Ittritfle Photon Emission Computed Tomography ( SPECT).
