12/09/13

The list of possible manufacturing company for Brick's Housing (BH) parts production is established:
- Partner Steel Co, Inc, Pocatello;
- Valley Sheet Metal (VSM) Technologies, Idaho Falls;
- Primear Technology, Blackfoot;
- Northwest wire EDM, Spokane, WA;
- Nelson Metal Technology, Payette, ID;
- Water Jet Cutting, Albuquerque;
All above companies have been contacted for quotes. Criteria were price and speed of production.

Brick's Housing (BH) parts (steel/AL/PMMA sheets) drawings is approved by Spielman (drawings #2013.1.001.0002-0009)

VSM Technologies: selected as manufactured company for BH parts (drawings #2013.1.001.0002-0009)

BH parts arrived at IAC and inspected. Kevin is going to assemble and weld them all together.

Cathode/anode drawings submitted to Spielman for approving (drawings #2013.1.001.0010-0017)
PMMA_Output_Sheet/Charging_Isolating_Tube drawings submitted to Spielman for approving (drawings #2013.1.001.0018-0019)
X-pinch driver assembly drawing with included cathode/anode submitted to Spielman for approving (drawing #2013.1.001.0020)
PARKER's Viton O-rings V0769-60 2-246 (2 pcs), ID 4 1/2 and W 1/8", selected for vacuum seal inside the cathode/anode section.

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\LESKER_C-0800-275_REASSEMBLED);

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:

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?;

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. Choose one from:
  - Corning 7056 Glass Viewport - 2.75" CF Flange, Accu-Glass Products, $125 [7];
  - Conflat Flange (CF) Zero Length Glass Viewport 1.5 inch to CF 2-3/4 inch, Ideal Vacuum Products, 179.95 [8];
  - 2 3/4" CF flange Sapphire Viewports, Lesker part #VPZL-275SW, $650 [9];
  - Note: this flange will be used for visual x-pinch observation. Later this flange can be replaced by x-ray window;
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);

Can we use cross instead of cube? (A: Cross - not, but reduced cross - yes)
Do we need to use Cu gasket to seal CF flange? If so, we need a lot of them for every shot.(A: yes, we need to use Cu gaskets);
O-ring in PMMA ~3 mm. Locate position and include in drawing. (done)
Buy LESKER reducing cross, RACL60 (done, Dec 30, 2013, expected delivery Jan 16, 2014);
Include all taped holes in drawing;
Include groove for two o-rings into the isolating output PMMA drawing, #2013.1.001.0018
