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)

Ta#37-LP-SIS (w.o#38634-5)

Filled with 400 Ta foils (25/pk), 4.0 cm in length.  Total mass + Ta wire = 42.32g.  The heat shield was assembled and tested, and the standard salts were added.  Target was installed in the test stand on Jun 1, 2011.  

Fri Jun 17 09:19:46 2011: The following salts have been added: Li, Na, Rb @ 10uL, K @ 5uL, Cs @ 15uL, and Be @ 10uL.

Wednesday, July 06, 2011, 14:08:  TM1 is still under repairing.  It was tested at the test-stand. Target is on the shelve and ready to be used.

Tuesday, July 26, 2011, 15:58:  Salt added before going into the hotcell: Li,Na,Rb,K,Cs.  Target is ready to be used for TM1 test.

Wednesday, July 27, 2011, 10:48:  It was found that the extraction electrode had some arc marking on it (see attachment: EE).  Investigating... 

Wednesday, July 27, 2011, 12:51: After further investigation on the extraction electrode,  we found some black and blue(or green) deposit on the outside surface and inside of the EE.  This deposit is most likely copper oxide, which formed during the HV test.  The EE was removed, and wiped clean with methanol.  (see attachment: EE_CuO).  This target will be used in TM1. 

Friday, August 26, 2011, 09:48:  As per Friday Aug 26 TIS meeting, bNMR is very satisfied with the beam; the count rate is very stable.

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

Thu Apr 7 15:32:32 2011:

Target oven - w.o#38481-3.

Packs of Ta foils were previously prepared by Vicky H.

Marik loaded the target:  400 of 0.025mm foils (25 foils/pk) in 3.5cm length.  (Recommended length 4.0-4.5cm; If too closely packed, wires get squeezed and snapped)

Average mass per discs = 0.105g

Total mass (Ta+wire) = 45.06g

Disc area = 2.12cm2

Ta thickness = 21.25g/cm2

Thu Apr 28 :

Target heat Shield (w.o 38303-4) cleaned

Target is now assembled by John and Rick

Megger Test Performed:

TA-->HS = 540V, OL

TA-->EE = 540V, OL 

HS--> EE = 1049V, OL

Leak Check OK

*SIS restraint used in this target ion source

Mon May 9 10:32:40 2011:  Standard salts added: Li, Na, Rb @ 10uL, K @ 5uL (but added 10uL), Cs @ 15uL.  Target will be going to the test stand.

Fri May 20 16:57:22 2011: 

Target was tested on the Test Stand but problems with the software (see Test stand elog). 

Standard salts added: Li, Na, Rb @ 10uL, K @ 5uL (but added 10uL), Cs @ 15uL, and Be @ 10uL.

Monday, July 18, 2011, 11:15:  Target ended on July 16.  The target was used online for an extra 2 weeks and performed very well.
