– BL 8.2.1 endstation frame– BL 8.2.2 endstation frame

• Moving the equipment out of and into the hutch

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 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.
