Engineering Division3
BL 8.2.1 and BL 8.2.2 Mini Hutches
Engineering Division4
Original Endstation Configuration for Both BL 8.2.1 and BL 8.2.2
Original endstation in the hutch frame Close-up
Engineering Division5
Rigaku Sample Mounting Robot and Automatic Dewar System
Rigaku sample mounting robot.
Automatic (open and close) sample dewar system.
Engineering Division6
Rigaku Robot and Dewar in Hutch
Robot mounted on cross beams bolted onto the frame.
Dewar mounted on to a stand.
Engineering Division7
Microdiffractometer MD2 and New Frame Added to BL 8.2.1
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 Division8
8.2.1 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 Division9
8.2.1 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 Division10
A spring loaded mounting stud will protect the equipment in case of earthquake.
8.2.1 Kinematic Mounts
The microdiffractometer will be mounted using a kinematic truncated ball /truncated cylinder arrangement.
Engineering Division11
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.
8.2.1 Frame
Engineering Division12
8.2.1 Frame FEA Deformation Results
Maximum deformation shown in ANSYS analysis is .00013 inch (3.3 microns).
Mass of the microdiffractometer is 310 lb (140kg).
Engineering Division13
New BL 8.2.2 Endstation Frame Added
Reconfigured endstation frame mounts the original BL 8.2.2 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 Division14
8.2.2 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 Division15
8.2.2 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 Division16
The ALM cross-slide will be mounted to these steel plates.
These steel plates will be used to mount the helium box.
8.2.2 Frame
The goniometer will mount here.
Engineering Division17
Maximum deformation shown in ANSYS analysis is .000157 inch (3.98 microns).
8.2.2 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 Division18

Engineering Division21
Moving the Original Endstation Out of the Hutch
With the side of the hutch removed the assembled 8.2.1 and 8.2.2 endstations can be lifted out of the hutch.
Engineering Division22
Moving the Original Endstation Base Out of the Hutch
With the side of the hutch removed the 8.2.1 and 8.2.2 endstation base frames can be lifted out of the hutch.
Engineering Division23
Moving Endstation Base into the Hutch
With the side of the hutch removed the new 8.2.1 and 8.2.2 endstation base stands can be lifted into position.
Engineering Division24
Moving Endstation into the Hutch
With the side of the hutch removed the new pre-assembled 8.2.1 and 8.2.2 endstation frames can be lifted into position on the base stands.
