Statement of Work

Mark circulated a draft of the statement of work recently. Eugene had some questions:

• Is the resolution stated consistent with the proposal?
• Is the schedule realistic?

Mark received a copy of Elton's scintillator specification from CLAS. Eugene suggested getting a copy of the CLAS12 specification from Dan.

PMT Purchase

Mark is collecting documentation on the phototubes we are considering for purchase. Details of the procurement process are being discussed.

Items on the TOF Wiki Page

Mark has added a few items to the wiki page:

• Chuck Hutton's 3D drawing of the TOF mechanical conceptual design
• Paul Eugenio's photograph of a recently made light guide
• a TOF cheat sheet, with nominal module counts and a sketch
• another schematic of the H10534 phototube, this one without the dynode read-out
