December 19, 2013
- LESKER reduced 4-way cross (C-0800-275, $890) found as a candidate for vacuum chamber [1];
- LESKER reduced 4-way cross drawing downloaded and incorporated into SolidWorks (assembly file Lesker_C-800_275\C-0800-275_reassembled);
- LESKER reduced 4-way cross redesigned to match our x-pinch driver (drawing file Lesker_C-800_275\2013.1.001.0030);
December 20, 2013
- Some changes to parts have been done to accommodate LESKER redesigned cross:
- 1) for Al output plate, the inner cut increased from 4.5 diameter to 10" diameter to match the cross (drawing #2013.1.001.0008);
- 2) for anode can, the slot size increased from 0.4" to 0.5" to march x-pinch wires length (drawing #2013.1.001.0014);
- Reassembled LESCER cross drawing submitted to Spielman for approving (drawing LESKER C-0800-275_REASSEMBLED)
- X-pinch driver assembly drawing with included cathode/anode/cross submitted to Spielman for approving (drawing #2013.1.001.0021)
- LESCER cross and new assembly drawings is approved by Spielman:
December 30, 2013
- LESKER reduced 4-way cross (C-0800-275, $890) is ordered [2]. 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 [3]).
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 [4]
- 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
Other parts we need for vacuum chamber are:
- flanges:
- 8" fixed blank CF flange, Lesker part #F0800X000N, $125 [5]. Note: I would cut this flange in the middle to reduce the weight twice from 12 -> 6 lbs;
- 2 3/4" fixed bore 1.63" CF flange, Lesker part #F0275X175N, $15 [6]. Note: this flange will be used for x-ray diode's mounting;
- 2-3/4" CF flange viewport window. Note: this flange will be used for visual x-pinch observation. Later this flange can be replaced by x-ray window. Choose the cheapest (first) one:
- gaskets [10]:
- 1/4 Hard OFHC Copper Gasket for 2-3/4" CF flange, Lesker part #GA-0275, set of 10, $26.40;
- 1/4 Hard OFHC Copper Gasket for 8" CF flange, Lesker part #GA-0800, set of 10, $75.00.
- fasteners scroll down:
- 5/16—24 x 2-1/4" Bolt & Nut Set, Lesker part #HBS31224225, set of 25, $37.58 (for 8" flange up);
- 5/16—24 x 1-3/4" Bolt Kits, Lesker part #HBK31224175, set of 25, $30.60 (for 8" flange Al plate connection), (need 1" length);
- 1/4—28 x 1-3/8" Bolt & Nut Set, Lesker part #HBS25028138, set of 25, $29.38 (for 2-3/4" flanges);
- Total quote is xxx.xx plus shipping.
January 02, 2014
- Al output plate drawing #2013.1.001.0008 is updated to accommodate vacuum chamber's cross (11" cut changed to 8" and added slot cuts for small flanges);
- Reassembled Lesker cross drawing #2013.1.001.0030 is updated (file name changed and added some dimensions for clarity);
- Assembly drawing #2013.1.001.0021 is updated for clarity;
January 02, 2014
PMMA's o-ring design
- o-ring material
- Viton (V1436-75, V1475-75, V1476-75)
- Assumption made: viton = fluorocarbon, hardness we nee 70-80
- o-ring size nominal: ID=4-1/2, OD=4-3/4, W=1/8;
- o-ring size actual: ID=4.484", W=0.139";
- grove shape and dimensions
- chart 4.3 of section IV - static o-ring sealing of Parker o-ring handbook;
- groove shape
X-pinch driver fabrication to do list
- Can we use cross instead of cube? (A: Cross - not, but reduced cross - yes);
