CryoTigers

On one occasion, the hose of the StanCam CryoTiger sprang a leak. The location of the leak seems to have been at exactly where the hose leaves the springs that connects it with the telescope rotator. The hose was repaired at a workshop on La Palma. The repaired hose has been cleaned inside with acetone and dried with compressed air. Then one end was sealed and again using the compressed air and a bucket of water the repair was checked for leaks and none found. A new connector was fitted to the end of the hose to replacing a known damaged one.

We have several CryoTiger gas bottles in various location around the telescope. This gas is highly inflammable and proper storage is required. Looking in to this, the best and safest solution is to store the bottles outside in suitable metal cabinets. Cabinets are being sourced.

Two new 20lb bottles of PT13 gas have been ordered along with a pair of filter dryers for the compressors. The filters have arrived but the gas is delayed due to problems with the transport.
