Summary of Present Filter Status (17 May 2000)
The
following bi-directional DCOPS sensors have been constructed, tested, and
verified as potential ISR tape configurations.
Hyperlinks lead to .pdf files of best data set taken. The quality of the
LDM determined many of the characteristics of peak shape; in fact quality of
the vertical beam was so poor far measurements of the peaks (<10m) were
essentially not useable. I have assumed
that the vertical LDM can eventually be tuned to the same quality as the
horizontal LDM. Hence, plots of far
measurements utilize only the horizontal LDM line source.
Sensor
Location*:
es1/10 80mm/1400mm
es2/9 300mm/14529mm
es5/6 3619mm/9801mm**
es4/7 3864mm/10726mm*** (Window 5)
es4/7 3864mm/10726mm*** (Window 6)
* Sensor location is given in from LDM to
midpoint of DCOPS CCD window
** Sensor location 3619mm/9801mm should be
moved to 5800mm/8800mm for CERN ISR.
The filter solution presented is for
3619mm/9801mm.
*** It
is presumed es4/7 solution will work for es3/8 (3860mm/10970mm), but this has
not
been confirmed empirically.
Notes:
========================================
CCD Window
1 80mm/14000mm locations
14000mm
side = orange filter + yellow tape
80mm
side = 1 yellow, 1 brown, 1 yellow tape
We also
required a hut + black strip on top of wedge
========================================
========================================
CCD
Window 1 300mm/14529mm locations
300mm =
1 yellow, 1 brown, 1 yellow
14529mm
= orange filter + yellow
We also
required a hut + black strip on top of wedge

CCD
Window 5 3619mm/9801mm locations
9801mm
side = 1 red
3619mm
side = 1 red + 1 white
no hut
needed

========================================
CCD
Window 6 3864mm/10726mm locations
10726mm
side = 1 red
3864mm
side = 1 red + 1 white
no hut

*It
seems the lower ccd, the one face up toward the florescent
lights
is almost at saturation on background.
Clearly a hut is
needed
here. THIS IS PRESUMED TRUE FOR CCD
WINDOW 5 (at the
3619mm/9801mm
locations).
