Laser Test Bench
We are developing a laser test bench to study possible space point distortions in a MPGD module for the Large Prototype TPC. The test bench consists of
- a ultraviolet laser pulser,
- a collimator with manual intensity control capability,
- a test box for the MPGD module with ALTRO readout,
- and a beam dump.
See the picture below:
The test bench will be covered by a black box for safety. Hand drawings of the black box are available from the following links:

and a description of its desing is given in this note (in Japanese).
A reference document to be submitted to the KEK safety office is here.
