A2D2 water Depth

A2D2 Operational Meeting Michael Geelhoed ESH&Q Meeting Action Items 1) A2D2 address Ozone Production measurements Conduct measurements, analyze reliable data Michael G, Jon Ylinen, Rob Bushek, Jonny Staffa Need to develop a Beam Study plan Complete January 31st 2018 Talked last week looking for time in February to complete, has better instrumentation 2) A2D2 Cave Vesda Alarm Response Document Talked to FFD and Fire techs for proper terminology Michael and Jon Ylinen Complete January 3rd 2018 3) A2D2 Clinac Breaker Off Document Living document to include the 3 conditions thus far Michael and Sue to address any other conditions Complete January 3rd 2018 4) A2D2 Absorbed Dose Document Establish parameters of running A2D2 for Machine Study Michael, Sue and Jon Complete January 3rd 2018

Still need to interact with Sue on how to proceed, I think we have the material in mind (water, aluminum, concrete) but do we need more? 5) A2D2 Radiation Awareness Document For our visiting potential partners Sue and Michael to assist Complete January 3rd 2018 Still awaiting this document from Sue 2 Issues with HABs CHW Two weeks ago we switched over to the ICW heat exchanger and breakered off the Chiller We developed an issue with low back pressure on the system (Return) The Return pressure should be 50 psi, last week it was 0-8 psi Called in Fermilab experts, Emil and Lee, no luck for fix Jim from Roberts Environmental graciously came out Determined it is the makeup pump with bad pump Currently we have: Breakered back on the chiller, to turn on internal heaters Asked Roberts for a quote to repair makeup pump Asked Roberts for a Service and PM Quote for a bank of hours This should cover the CHW system and the old chiller
