Target came out from the glovebox and transported to the cold lab for assembly.  During the assembly, one of the screw-heads for the heat-shield broke (see attachment#1: broken_screwhead). 

The target was leak checked and fine. 

Target is going back to the glovebox to be kept under Ar until RH is ready (see attachment #2: UCx#2).

UCx#2 run was finished last week.  

Target was moved from ITW to south hot cell, and stored in a bucket under argon feed.

The target is now in the test-stand, and by next week Tuesday, it should go in the Hotcell.

 Monday, June 04, 2012, 16:56

The target was tested in the Test-stand.  The EE was inspected and a small amount of deposit was discovered after the test (the same stuff was found on Ta#36),  see attachment #1.  The samples were collected and will be analyzed through SEM/EDX/XRD.

The EE and the common plate were cleaned with methanol and were assembled back.

The target is ready to go in the Hotcell tomorrow, June 05.

 Monday, November 05, 2012, 16:42

The deposits on the EE and CC were analyzed using XRD

On the EE, it was mainly copper hydroxide nitrate, Cu2(OH)3(NO3). (see attachment #2)

On the CE, it was mainly tantalum, Ta. (see attachment #3)

Thu Mar 31 15:19:51 2011:  SiC#25 was made sometime in December of 2010.  It is now in the target module and ready to be conditioned. 

Mon Apr 18 18:17:05 2011: It was found later that no salt was added to this target after it came out from the test stand.  However,  there were enough 40Ca and 39K  for tuning (See attachment#1 for the big mass scan).  Once the P+ is back, the yields will be measured.

Fri Apr 29 15:30:26 2011:  Low 27Al was ionized from the surface for some reason.  However, after the green laser was shone into the extraction tube, more 27Al was produced.  Then, the laser was turned off, the target continued to surface ionizing 27Al.  There could be a blockage from the rhenium (Re) ionizer foil.  Jens L. will investigate this further and do a test with the lasers and the rhenium foil.

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.  

Ta-LP-SIS (w.o#38634-2)

Target consists of 400 Ta foils, 4.4 cm in length.  Total mass + Ta wire = 40.87g.

Thursday, July 07, 2011, 15:43:  Begin target assembly. 

Friday, July 08, 2011, 14:24: assembly completed.  Std stds added for test-stand: Li, Na, Rb, K, Cs.

Friday, July 15, 2011, 09:09:  Target currently in test-stand.  Will come out on Monday next week.  Need to add std salts + Be. 

Monday, July 18, 2011, 10:58:  Target removed from test-stand.  Std salts added (Li, Na, Rb, K, Cs) & Be (as requested by Jens).  Maico D.V will do a final inspection on the target before it goes into the hotcell
