* LESKER reduced 4-way cross (C-0800-275, $890) is ordered [http://www.lesker.com/newweb/flanges/fittings_cf_crosses.cfm?pgid=4wayreducer]. Expected delivery id January 16, 2014. Comments: this one we will cut and reassemble later in the way we need. Just to remind, I plan two use one 8" flange for plate connection, one 8" flange for x-pinch access and vacuum pump connection, one 2 3/4 flange for x-ray diagnostics and one 2 3/4 flange for x-ray output.
 
−
 
−
* for x-ray windows we  can use Beryllium window (available from Moxtek in 1-1/3 and 2-1/8 CF flanges [http://www.eurotek-general.com/upload/PDF/Moxtek/DuraBeryllium%20Windows%20in%20ConFlat%20Flanges,%20WIN-TECH-1001.pdf]).
 
−
[[File:Be transmission data1.jpg | 100 px]]
 
−
 
−
For 2-1/8 CF flanges x-ray window, we will need Zero-Length Reducer Flange (from 2 3/4 to 2 1/8), like [http://www.lesker.com/newweb/flanges/flanges_cf_reducer.cfm?pgid=std]
 
−
 
−
* '''can we use quartz window instead of beryllium?''' (we can probably borrow one from IAC stock);
 
−
* do we need RIGHT NOW x-ray window? A: no, we will need just glass viewport for x-pinch visual observation;
 
−
 
−
==December 31, 2013==

−
==January 07, 2014==
 
−
talked with R. Spielman:
 
−
*o-ring: the hardness of o-ring doesn't matter;
 
−
*gaskets:
 
−
** use Viton square gaskets for large flange instead of Cu, it could be used many times;
 
−
** cutting the large twice is OK;
 
−
** small flanges: using one blank and one veiwport is OK. Note: buy two blank (%15 each) and use viewport if available from IAV stock;
