-   Originally designed for Sector 2

-   **Insertion Device Integral Shutter**

-   **Pink Beam Photon Shutter**

-   **Pink Beam Safety Shutter**

-   **Pink Beam Fixed Mask**

-   **Pink Beam Collimator**

**Beam Line locations:**

-   10 Shutters total

**[2ID-A:]{.underline} P9-30 Pink beam, D-E beam line, 0.3 degrees from
the axis of the ID beam**

**P9-40 Pink beam, C beam line, 2.5 degrees from the axis of D-E
branch**

**P9-20 Pink beam, B beam line, 5.0 degrees from the axis of D-E
branch**

**[Horizontally deflecting mirrors]{.underline}**

**D-E beam line - Maximum energy of 40 keV**

**C beam line - Intermediate energy range of 0.5 to 3 keV**

**B beam line - Intermediate energy range of 0.5 to 4 keV**

**[2ID-E]{.underline} P9-50, Pink/Mono beam**

**[4ID-A]{.underline} P9-40, Pink beam, C branch**

**[8ID-A]{.underline} P9-30, Pink beam**

**[8ID-D-MH-1]{.underline} P9-50, Pink beam**

**[9ID-A]{.underline} P9-50, Mono beam**

**[34ID-B]{.underline} P9-30, Pink beam**

**[34ID-D]{.underline} P9-30 White beam** A.R. The mask in 34-ID-B has a
restriction to operate only to gaps of 15 mm due to thermal effects. The
ID gap has currently an administrative limit of 15 mm gap and a hardware
limit set for 14.8 mm.

-   **20, 30, 40 and 50 is only a designation - denotes physical
    difference -- see drawings**

**Flange size**

**Port location**

**Vacuum Chamber -- All - flange to flange length -- 622 mm**

**P9-20 -- in line w/beam -- 4 ½" flange & 6" flange, Pump out port --
8" flange (side)**

**P9-40 - in line w/beam -- 4 ½" flange & 6" flange, Pump out port -- 8"
flange(bottom)**

**P9-20 & P9-40 Design difference -- (pump out port position)**

**P9-30 -- in line w/beam -- 6" flanges, Pump out port -- 8" flange
(side)**

**P9-50 -- in line w/beam -- 8" flanges, Pump out port -- 8" flange
(bottom)**

> **Pump out port - 8" -- decreased conductance**
