Review Allan DeMello 12/13/2006
2
Outline

• Original configuration
• Rigaku sample mounting robot and automatic dewar
  system
• New endstation configurations requirements
• Deliverables from engineering
• BL 8.2.1 endstation frame
• BL 8.2.2 endstation frame
• Moving the equipment out of and into the hutch

Original Endstation Configuration for Both BL
8.2.1 and BL 8.2.2

Rigaku Sample Mounting Robot and Automatic Dewar
System
Rigaku sample mounting robot.
Automatic (open and close) sample dewar
system.
6
Rigaku Robot and Dewar in Hutch

• Robot mounted on cross beams bolted onto
  the frame.

Dewar mounted on to a stand.
7
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.
8
8.2.1 Frame Requirements
Requirements - Vibrational stability
to within 5 microns. - Natural
frequency of system above 10 Hz
Rigid coupling of the helium box and the
microdiffractometer through the frame is required.
9
8.2.1 Frame Requirements
Endstation must have to ability to tilt.
A common strut axis is created to minimize
parasitic motion during tilt.
Motorized strut mounted here will be an
option to tilt the endstation.
This strut will be used to tilt the
endstation.
10
8.2.1 Kinematic Mounts
The microdiffractometer will be mounted
using a kinematic truncated ball /truncated
cylinder arrangement.
A spring loaded mounting stud will protect
the equipment in case of earthquake.
11
8.2.1 Frame
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.
12
8.2.1 Frame FEA Deformation Results
Mass of the microdiffractometer is 310 lb
(140kg).
Maximum deformation shown in ANSYS analysis
is .00013 inch (3.3 microns).
13
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.
14
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.
15
8.2.2 Frame Requirements
Endstation must have to ability to tilt.
This strut will be used to tilt the
endstation.
A common strut axis is created to minimize
parasitic motion during tilt.
Motorized strut mounted here will be an
option to tilt the endstation.
16
8.2.2 Frame
These steel plates will be used to mount
the helium box.
The goniometer will mount here.
The ALM cross-slide will be mounted to
these steel plates.
17
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.
Maximum deformation shown in ANSYS analysis
is .000157 inch (3.98 microns).
18
8.2.1 and 8.2.2 Base Support Stand
BL 8.2.2 base support stand.
BL 8.2.1 base support stand.
19
8.2.1 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.
20
8.2.2 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.

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.
22
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.
23
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.
24
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.
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.
26
BL 8.2.2 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
