-- Bill: there are problems with the water chiller; Mike Sprouse suggested several things: to measure the temperature at the input and output of the chiller and estimate the heat produced by the chiller itself. He suggested also to clean the heat exchanger. Another option is to find another water chiller. After the meeting Bill with Casey found that the water chiller itself is producing a lot of heat, therefore Bill borrowed another chiller from the accelerator people. So, the plan now is to replace the water chiller which will happen at the beginning of next week.
+- Bill, Casey and Beni performed the test of one loop of the cooling system. 22 pre-amps were attached to the cooling tube and powered with LV. The flow (at the right pressure) appeared to be in a good agreement with the ANSI model, however the temperature drop between the end and the beginning of the loop was 1.2deg instead 2deg as expected from the model. We discussed possible reasons for that:
