Paper Abstract

Demountable photocathode X-ray streak camera developed for X-ray diagnostics in ICLF experiments is described. The system can be installed to the experimental chamber via gate valve furnished at one end of the front end chamber, the other end of which is connected to the streak tube. Remarkable features of the system are demountable photocathode scheme which enables to change the photocathode very easily and quickly, demountable accelerating mesh electrode, gate valve which enables the system to operate independently from the experimental chamber, differential pumping scheme which keeps the_vacuum_in the streak tube better than 10 6 torr while the front end is evacuated down to 10 ~ 4 % 10 05 torr through the gate valve and data taking scheme such as a film back or SIT TV camera combined with a temporalanalyzer. Typical performances of the system are characterized by the sensitivity of the photocathode to the soft X;ray ranging from 100 eV to 10 keV because of a 300 Å Au photocathode deposited on a 1000 Å Parylene film, the streak sweep rate of 1 ns/15 mm to 10 ns/15 mm, the streak trigger delay time of 20 ns to 30 ns and the excellent low trigger jitter less than ±20 ps. Simultaneous gating of the photocathode of the streak tube and the MCP in image intensifier gives low back ground output image. Preliminary test of the system showed that the system has a temporal resolution of 17 ps and a limiting dynamic spatial resolution of 20 1p/mm along the 10 mm useful photocathode slit at the fastest sweep rate of 1 ns/15 mm.
