INTEGRAL SHUTTER defined:
A device that integrates a white-beam stop, two monochromatic-beam shutters, a safety stop and a collimator into one assembly.

P6 Shutters at the APS
P6-20 shutter is the original design. 1-BM-A P6-20 Integral Shutter. 2-BM-A P6-20 Integral Shutter. 12-BM-A P6-20 Integral Shutter
- locked in mono mode. 17-BM-A Originally a P6 shutter
- locked in mono mode.Significantly modified P6 shutter.

P6 Components/function White Beam Photon Stop – absorbs high power x-rays
in mono mode. (2) Mono-beam Shutters – redundant protection,
absorbs mono beam. Safety Stop – blocks bremsstahlung radiation in mono
mode. Collimator – 18 x 120 mm aperture, passes white or
mono beam depending on mode setting. Kirk-key interlock system - guarantees proper
component operation.

P6 & P4 Integral Shutters
![Page 15: 1 P 6 S H U T T E R S By RICK SPENCE September 6, 2005.](https://reader030.fdocuments.net/reader030/viewer/2022032723/56649f515503460f94c74932/html5/thumbnails/15.jpg)

P6 vs. P4 SHUTTERS–Similarities:
The P6 shutter is very similar to the P4 shutter.
Both are integral shutters & include the same internal components.
The P6 and P4 integral shutters were the first shutter used for BM/ID beamlines at the APS, at Sectors 1 & 2.

16
P6 vs. P4 SHUTTERS -Differences:
P6 – Used in BM beamlines only, P4 – ID only. White Beam Photon Stop design
(P6 – block, P4 – hockey stick) Collimator opening size
(P6 -18x120mm, P4 -18x80mm) Design Geometry

Reliability of P6 Shutters Originally designed for 10 years. 1-BM and 2-
BM P6 shutters in operation for 10 years and counting.
Shutter Stats (response time) available thru EPICS for not only PS1/PS2 but for other beamline shutters as well.

Expected failures for P6 shutters (& other shutters)
Failure of seals, resulting in restricted operation and/or vacuum leaks.
Failure of air actuators. Failure of bellows, resulting in vacuum
leaks.
