Hi All,
We will have a beam line meeting at 10am Monday morning in the Group C conference room.
Agenda and minutes of last meeting:
Agenda:
A) Hall B work - update: Stepan and Francois
B) Target - measurements on target materials - Clive
Graphite #1: 0.04411 g/sqcm
Graphite #2: 0.04402 g/sqcm
(If it were, in fact, 250 microns thick, then density would be 1.76. This is in the expected range.)
Tungsten 4 micron #1: 7.8125 E-3 g/sqcm; no pinholes seen
Tungsten 4 micron #2: 7.8287 E-3 g/sqcm; some pinholes, near middle and edge
If density is the table value of 19.3, thickness is 4.056 microns.
Tungsten 8 micron #1: 1.495 E-2 g/sqcm; pinhole near middle, and edge
Tungsten 8 micron #2: 1.520 E-2 g/sqcm; lots of pinholes -- see attached photograph
If density is 19.3, #1 thickness is 7.746 microns, #2 is 7.88 microns.
