http://www.jlab.org/~zwzhao/polhe3/product/

== for purchase ==

*2+1 of Stanford SR560 (buy or fix) 
*3 Agilent 33220/33250A or Stanford DS345
*1+1 lock-in amplifier
*1 RF amplifier (check it)
*1 match box (???)

== diffusion rate test ==

making another small RF coil and connect it into the system

* 1 RF coil, 
* control can be shared with NMR RF, 1 function generator, 1 amplifier, 1 capacitor, and cables

== convection flow ==

* 1 heater and its control
** cord HTC-030 $26 0.9m http://www.omega.com/ppt/pptsc.asp?ref=HTC
** tape with control HTWC101-004 $111 1.2m http://www.omega.com/ppt/pptsc.asp?ref=HTWC_Series
** Both use Nickel-Chrome 60 wire (not magnetic, refer to http://www.omega.com/ppt/pptsc.asp?ref=NI60, http://en.wikipedia.org/wiki/Nichrome, and http://www.dianresi.com/ArticleShow.asp?ArticleID=153)
** other material is fiberglass and silicone rubber etc
* 1 zapper coil and its control (can be shared with NMR RF)
* 1 set of NMR pick-up coils, 1 pre-amplifier (Stanford SR560), 1 lock-in amplifier (Stanford SR844).
* RTD
** thin film surface mount SA1-RTD-80 $56 http://www.omega.com/ppt/pptsc.asp?ref=SA1-RTD
** thin film element F3105 $19 http://www.omega.com/pptst/F3105_3100_W2100_2200.html
** thin film element F2020-100-A-100 $1.75 http://www.omega.com/pptst/F1500_F2000_F4000.html
** The RTD elements all use platinum coated nickel lead wires, due to their small size, the magnetic effect is small. The SA1-RTD-80 has long nickel-plated copper wires which may be a problem.
** We need to use Class A RTD to have about 0.5C error above 200C, clas AA doesn't help because its precision drops above 150C, refer to http://www.omega.com/toc_asp/frameset.html?book=Temperature&file=RTD_Gen_Specs_Ref
