=Definitions=

According to http://www.set3.com/standards.html

Originally Federal Standard 209E defined a class 10,000 clean room based on the particle counts given below. A class 10,000 clean room is currently defined as an ISO 7 clean room using the ISO standard 146441.

Llim: /* 2/2/12 */

Chamber is being rotated this morning to start potting on the next endplate. All plugs and standoffs have been glued on this endplate.

There were clearance issues as we were trying to position the chamber to pot the other endplate.

[[file:20120202_WithRail.jpg | 400 px]]

The magnet rail needed to be removed so that we could position the chamber properly.

[[file:20120202_WithoutRail.jpg | 400 px]]

Also, we are limited to how much we can rotate the chamber.

[[file:20120202_Clearance.jpg | 400 px]] Camera settings give this image a yellow hue...sorry :P

Because of this clearance issue, we couldn't even rotate the chamber 270°, but I don't even know if we will ever need to rotate the chamber this much.

We got around this by shifting the entire chamber/strongback/upper shaft forward several inches.

=2/6/12=

Potting has been completed.

Mylar window installation will begin tomorrow.
