TIPC was founded in 1999, on the basis of• The former Inst. of Photographic Chemistry of CAS• The former Cryogenic Laboratory of CAS (which had 2/3

cryogenic people in China, ‘Cryogenic National Team’)• Some relevant departments of IC and IP of CAS

TIPC has • over 350 professional staff & over 300 MS and Ph.D. students• 6 Academicians of CAS and 59 full professors and equivalent

Key research areas of TIPC (6 research centers & 26 groups)• Optical functional materials and device• New synthesis technologies for green chemistry• Energy materials and new technologies • New technologies of cryogenic engineering (2 centers & 7 groups)

1. Introduction of TIPC

• My group, the Large Cryogenic Engineering Group (LCEG), takes the design, construction and commissioning of the cryogenic systems in the Large Scientific Project in China and oversea, especially in the HEP field as our main work

2. Introduction of LCEG

3. Research Activities - BEPCII


2 cavities, 500 MHz & one cell each Cavities are made of niobium and will work at 4.5 K. Cavity resides inside a stainless steal liquid helium vessel of 290 liter. Thermal loads include about the 30 W static load and 84 W dynamic load.


A pair of SC interaction quadrupoles magnets is used Consisting of independent quadrupole (SSQ), horizontal dipole (SCB, SCB or HDC) vertical dipole (VDC), Skew-quadrupole (SKQ) and three part atti-solenoid (ASI-3) windings
