SiC#29 HP-FEBIAD-CTL target description:

Total SiC foils = 510 discs

Total mass SiC + C_grv foils = 62 g (before sintering, expecting ~13% loss of organic mass after burnt off)

Average mass SiC/disc (without C_grv) = 0.0892 g

Average thickness SiC (without C_grv) = 0.21mm

No Rh foil and salt added for this run.

See attachment #1 for the density measurement.

Target is currently in the Test-Stand. Once it's tested; it is ready to go online.

Happy Beaming!

Friday, September 23, 2011, 17:03, Anders Mjos, SiC#26, HP-FEBIAD, ITE, TM4, 38295-9, 38307-8, Spent, Run finished

Friday, September 23, 2011, 16:54:

Cu-gaskets used for leak checking target had a leak rate of about 10^-8 10^-9 atm cc/sec. Replaced with silver plated SS gaskets and no leak detected above 10^-11 atm cc/sec.
The target can not hold high voltage when it is sitting on the jig. The insulator on the jig have reduced resistance over time (less than 1 G Ohm). All high voltage tests passed when target is tested not sitting on the jig.

Target is now in the test stand and pumping down.

After the test-stand, the extraction electrode showed some electric arcing mark, but no solid deposits were found. (see attachment#1: EE_after_teststand.jpg)

See attachment for the target specification.

The target has been used for operator training previously at the ISAC Test Stand.

9-pin connector was completed and grounded
RH gripper arms added to the heat shield

Note:

This target was built in 2011. The endcaps were replaced after they got vaporized in Evap#1 during the sintering process, and the target was re-conditioned.

See elogs for more details:

https://elog.triumf.ca/TIS/Evaporator_1/20

The target was inspected and was good for online use.

Total SiC foils = 555 discs

Total length (packed) = 17.5cm

Total SiC mass (plus graphite foils) = 52.902g
