* LESKER reduced 4-way cross (C-0800-275, $890) is ordered [https://wiki.iac.isu.edu/index.php/File:Order_Report_from_The_Kurt_J.pdf], [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;

'''PMMA o-ring and groove design'''
 
−
 
−
*o-ring material we are needed:
 
−
** Viton (V1436-75, V1475-75, V1476-75);
 
−
** assumption made:
 
−
*** viton = fluorocarbon;
 
−
*** hardness we nee 70-80;
 
−
 
−
*o-ring size we are needed:
 
−
** nominal: ID=4-1/2, OD=4-3/4, W=1/8; 
 
−
** actual: ID=4.484", W=0.139";
 
−
** Parker size number 2-246;
 
−
 
−
*o-ring we are needed:
 
−
** V1436-75 2-246;
 
−
** V1475-75 2-246;
 
−
** V1476-75 2-246;
 
−
 
−
*grove shape and size design:
 
−
** chapter 4.3, section IV - static o-ring sealing, Parker o-ring handbook.pdf:
 
−
*** groove shape standard;
 
−
*** ID=4.484", W=0.161", OD=4.806", Depth = 0.104", R=0.017", Finish = 16 RMS uinch;
 
−
** also see Eriks groove/o-ring calculator [http://oringcalculator.eriksgroup.com/#], pdf report [[File:03012014162515.pdf]];
 
−
** assumption made:
 
−
*** external pressure;
 
−
*** ID(groove) = ID (actual o-ring size);
 
−
*** o-ring deformation is about 25%;
 
−
 
−
* o-ring's grooves included into the PMMA drawing #2013.1.001.0018;

==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;
 
−
*vacuum chamber, anode, cathode drawings all are looking good;
 
−
 
−
parts we need to order extra for vacuum chamber:
 
−
* flanges:
 
−
** first look at IAC; if not available, than buy:
 
−
** 8" fixed blank CF flange, Lesker part #F0800X000N, $125 [http://www.lesker.com/newweb/flanges/flanges_cf_304SS.cfm?pgid=8in];

−
* use Viton square o-ring to seal all flanges;
 
−
* fasteners, I will look at later;
 
−

==January 10, 2014==
 
−
talked with Kevin about vacuum chamber and anode/cathode:
 
−
 
−

−
** 8" CF non-rotatable flange 6" pipe;
 
−
** 8" CF blank flange;
 
−
** Kevin recommended Duniway stockroom corp;
 
−
 
−
* order material (Grainger) and then we will do it at IAC;
 
−
** ask ParnerStill (Pocatello) about naterial, but they will probably ask what grade of brass we need;
 
−
 
−
* 8" flanges from MDC Vacuum have been ordered [https://wiki.iac.isu.edu/index.php/File:MDC_Vacuum_011014.pdf]:

−
*vacuum chamber: all parts are ordered and after its arriving we start to fabricate the vacuum chamber;
 
−
*cathode/anode:
 
−
**should be approved? yes, and also need to include current monitor in anode cane drawing;
 
−
**identify and buy brass cuts; use naval/hard brass, should be easy to machined and inexpensive
 
−
**after vacuum chamber will be fabricated, update, if needed, drawings and fabricate anode/cathode parts;
 
−

**make as reference plates the bottom and front of housing and update cathode plate drawing 2013.0001.0010 to center cathode vs anode;
 
−
**need some extra parts (tube ID=2" OD=2.5") for centering;

'''Found that housing plastic sheets we ordered do not have precise thikness we asked and wanted:'''
 
−
*They are really 0.45-0.49" and 0.23-0.235" instead of 1/2 and 1/4 as we expected to be;
 
−
*Most likely that plastic supply companies switched to metrics (mm) standard. But they still specify thickness in inches, but real thickness is less, like 0.47" instead of 0.5". Some company specify this fact [http://www.eplastics.com/Plexiglass_Acrylic_Sheet_Clear];
 
−
*Found company which probably still supply plastic in inches we need [http://www.professionalplastics.com/];
