First optics monochromator performance and other HHL optics R&D

PDF Version Also Available for Download.

Description

To procure a high heat load crystal monochromator system that can deliver the undulator beam to the sample with minimal loss of brilliance with: APS operating at 7 GeV and 100 mA; a 2.5-m ID with k=2.17 (4.2 keV first harmonic). The measured data and modeling indicate that a crystal in the inclined geometry (with appropriate inclination angle) cooled with liquid gallium will meet the needs of this near-term goal. The following should be noted: liquid gallium has been selected as the coolant for its superior physical properties (as compared to water) such as thermal conductivity and high boiling point. ... continued below

Description

To procure a high heat load crystal monochromator system that can deliver the undulator beam to the sample with minimal loss of brilliance with: APS operating at 7 GeV and 100 mA; a 2.5-m ID with k=2.17 (4.2 keV first harmonic). The measured data and modeling indicate that a crystal in the inclined geometry (with appropriate inclination angle) cooled with liquid gallium will meet the needs of this near-term goal. The following should be noted: liquid gallium has been selected as the coolant for its superior physical properties (as compared to water) such as thermal conductivity and high boiling point. The inclined crystal geometry has been chosen for its reduction in surface power loading and improved heat flow. Design goals: fixed exit operation; 35 mm offset; tunable from 4-20 keV with Si (111); high vacuum (10{sup -6} - 10{sup -7} torr) compatible; design independent of final crystal configuration; and operation with 2.5 m ID @ 7 GeV & 100 ma. The mechanical/vacuum portion of the APS monochromator was delivered by Kohzu Seiki in January 1994 and we have begun testing of the mechanics. We also have motions (step motors, servo-motors,) encoders, gallium pump read=out, and vacuum pumps and read-outs under EPICS control.
