Engineering Division 1 HHMI 8.2.X Endstation Modification Review Allan DeMello 12/13/2006

Engineering Division 2 Outline Original configuration Rigaku sample mounting robot and automatic dewar system New endstation configurations requirements Deliverables from engineering –BL endstation frame –BL endstation frame Moving the equipment out of and into the hutch

Engineering Division 3 BL and BL Mini Hutches

Engineering Division 4 Original Endstation Configuration for Both BL and BL Original endstation in the hutch frame Close-up

Engineering Division 5 Rigaku Sample Mounting Robot and Automatic Dewar System Rigaku sample mounting robot. Automatic (open and close) sample dewar system.

Engineering Division 6 Rigaku Robot and Dewar in Hutch Robot mounted on cross beams bolted onto the frame. Dewar mounted on to a stand.

Engineering Division 7 Microdiffractometer MD2 and New Frame Added to BL Endstation Microdiffractometer MD2 replaces most of the original endstation equipment. Endstation base plate has the same footprint as the original base plate. No new holes to drill for the endstation. New holes needed for the dewar stand.

Engineering Division Frame Requirements Rigid coupling of the helium box and the microdiffractometer through the frame is required. Requirements: - Vibrational stability to within 5 microns. - Natural frequency of system above 10 Hz

Engineering Division Frame Requirements This strut will be used to tilt the endstation. A common strut axis is created to minimize parasitic motion during tilt. Endstation must have to ability to tilt. Motorized strut mounted here will be an option to tilt the endstation.

Engineering Division 10 A spring loaded mounting stud will protect the equipment in case of earthquake Kinematic Mounts The microdiffractometer will be mounted using a kinematic truncated ball /truncated cylinder arrangement.

Engineering Division 11 These steel plates will be used to mount the helium box. The microdiffractometer will be mounted to this steel plate using a kinematic truncated ball /truncated cylinder arrangement Frame

Engineering Division Frame FEA Deformation Results Maximum deformation shown in ANSYS analysis is inch (3.3 microns). Mass of the microdiffractometer is 310 lb (140kg).

Engineering Division 13 New BL Endstation Frame Added Reconfigured endstation frame mounts the original BL endstation equipment. Endstation base plate has the same footprint as the original base plate. No new holes to drill for the endstation. New holes needed for the dewar stand.

Engineering Division Frame Requirements Requirements: - Vibrational stability to within 5 microns. - Natural frequency of system above 10 Hz Rigid frame is required to mount the original endstation equipment.

Engineering Division Frame Requirements This strut will be used to tilt the endstation. A common strut axis is created to minimize parasitic motion during tilt. Endstation must have to ability to tilt. Motorized strut mounted here will be an option to tilt the endstation.

Engineering Division 16 The ALM cross-slide will be mounted to these steel plates. These steel plates will be used to mount the helium box Frame The goniometer will mount here.

Engineering Division 17 Maximum deformation shown in ANSYS analysis is inch (3.98 microns) Frame FEA Deformation Results Mass of cross-slide approximately 200-lb. Mass of goniometer approximately 125-lb. Mass of helium box approximately 40-lb.

Engineering Division and Base Support Stand BL base support stand. BL base support stand.

Engineering Division Deliverables Rigid upper frame, with tilt capability, to mount microdiffractometer and other equipment. Base support frame with motorized tilt option. Automatic dewar system support stand.

Engineering Division Deliverables Rigid upper frame, with tilt capability, to re-mount the original endstation equipment. Base support frame with motorized tilt option. Automatic dewar system support stand.

Engineering Division 21 Moving the Original Endstation Out of the Hutch With the side of the hutch removed the assembled and endstations can be lifted out of the hutch.

Engineering Division 22 Moving the Original Endstation Base Out of the Hutch With the side of the hutch removed the and endstation base frames can be lifted out of the hutch.

Engineering Division 23 Moving Endstation Base into the Hutch With the side of the hutch removed the new and endstation base stands can be lifted into position.

Engineering Division 24 Moving Endstation into the Hutch With the side of the hutch removed the new pre-assembled and endstation frames can be lifted into position on the base stands.

Engineering Division 25 Moving Rigaku Robot into the Hutch With the side of the hutch removed the Rigaku Robot can be lifted into position on the cross beams.

Engineering Division 26 BL Side of Hutch Removal Removal of the hutch side is not a trivial task. All of the various control panels will need to be detached from the hutch wall before it can be removed
