Dear Jim, Roy,

here is the sole source justification for the X-ray KB mirror system
you've agreed to procure. The quote is also included in the sole source
for easy access. I will follow up with another sole source for the mirror
today. If there are any issues to fix, let me (or Don) know.

Eric

-------------------------------------------------$ 17,100
2- One set of electrical components that control and support
one Kirkpatrick-Baez X-Ray Mirror Bender. The electrical
components comprise all Bipolar Stepping motors, motor
drivers and VME interfaces with cables. The cost includes
assembly, test and calibration with the mechanical assembly.
----------$11,500
3- 200 mm x 200 mm He Enclosure
----------------------------------------------- $ 4,534
----------------------------------------------------------------------------
---------Total Cost $33,134

The KB Bender unit as quoted consist of the following.
The complete system includes:
1) A pair of benders (Horizontal and Vertical) with each bender actuated by
four motors
(eight motors total). Two motors (Newport MFM stages) applying the up and
down stream bending moments, one motor (Newport MFM stage) translates the
mirror along its surface normal, allowing the mirror to be centered on the
beam and the fourth motor operates a cam tilt drive with an angular range of

about +/- 20 mrad (rotating about the center and surface of the mirror) used

for setting up the incident angle. The pair are held in mutual registration
by a common support to an adjustable tripod for mounting to a table.
2) Each bender is connected to a vacuum tight feed through with a rubber
O-ring and a jam nut that can seal the system within the He enclosure.
3) A set of ~ 50 ft driver cables.
4) An eight channel driver box that takes as inputs step and direction
through either two a "E500" like ribbon cable or two DB 25's.
5) A transition board for a VME crate supporting the use of an OMS 58 eight
channel stepping motor controller.
Note: Mirrors are not included with this quote.
A 200 mm x 200 mm He enclosure is available for $4,534.00.
The He enclosure is designed to be compact so that you could work close to
the end of the last mirror (200 mm )and still get a 45 deg microscope in to
view the sample.
Delivery will be 10 weeks from date of order.
Thanks for considering our services.
