3. A slide about organization Charter Science operations will begin with the completion and commissioning of the 100 tank array. We plan to keep the experiment continuously running and begin collecting scientific data to the extent that construction activities for the remaining 200 tanks allows. Science operations will be under the control of the spokespeople and collaboration board. Once science operations begin, a run manager and a deputy run manager will be selected by the spokespeople to oversee the data-taking and data management. Both the run manager and deputy run manager will become members of the tech board to provide an interface between the construction and science operations.

6. HAWC Collaboration April 2010 Budget intro Total construction cost (including contingency) -$12M –NSF $7M & DoE $2M –CONACyT Mexico $3M Incremental Science and Construction Support –Much of the effort by faculty will be redirected from other projects –NSF will be asked to provide post-doc, grad student and travel support for NSF groups –DoE will be asked to do the same for DoE groups and LANL –CONACyT plus Mexican universities will support the Mexican groups Operations (~$700k/yr) costs will be shared between US and Mexico

13. HAWC Collaboration April 2010 Operations (after completion) HAWC (like Milagro) is designed to be operated remotely. –The experiment can fully be controlled via network –Milagro had ~95% on-time (including pond work) Data is stored locally and transmitted to a Mexican and US data center We expect to have technicians at the site during the day for maintenance We expect students, post-docs and faculty to be there regularly We will have local (off-mountain) housing Much of the site upkeep will be done by the consortium

14. HAWC Collaboration April 2010 Operations Costs We plan to operate HAWC for 5 years with a probable 5 year extension Operations costs for Milagro were about $700k/yr This included the cost of filters, maintenance ( lasers, ups batteries, pumps, etc ), engineering and technician support It also included the disks to store data onsite and offsite. Data Storage/Processing costs: ~$200k/yr –~300TB/yr for raw and processed data –Servers, power backup, etc Local Expenses (Consortium fee, housing, etc) - ~$30k/yr Expendables (Filters, batteries, covers, laser parts) - ~$100k/yr Support Personnel (Technicians/Engineers/guards) = $300k/yr

15. HAWC Collaboration April 2010Manpower The HAWC collaboration consists of about 80 people (52 FTE), more than double Milagro which had ~30 people (~21 FTE) Strong technical expertise with Milagro & at high altitude site –Project engineer (M. Schneider) & tech (S. Delay) are from Milagro –Local technical support from INAOE and UNAM There is a very strong Mexican presence – lots of students who are funded to work on the project and who are already working on it. In the US we have expanded the collaboration to include Wisconsin, Utah, Penn State, Colorado State, Mich Tech, etc.. We are requesting incremental support from NSF and DoE support for LANL (UNM) plus engineering and tech support.
