G'day Jenny,
As you are no doubt aware, I have a 4th yr student working on an in-situ
stress rig to fit the XRD. It has come to my attention that you are
reluctant to allow him access to the XRD to measure the attachment points
for his rig. I have been somewhat remiss in not keeping you informed of
this project, but basically it is to design a rig that applies stresses to
foil samples whilst in the X-ray beam. It fits fully inside the chamber and
so does not compromise the safety interlocks or normal operation in any
way. The aim is that the rig be able to be very quickly fitted and removed,
in no mroe time than a normal sample. To do this, the attachmetn points
need to be measured accurately. These are to be the screws that attach the
clip that holds the 'normal' samples on. I would be obliged if you could
allow Dennis or our workshop staff to remove the screws holding the clip on
so that they can make this measurement. There is absolutely NO danger of
disrupting the normal operation of the instrument by doing this and at no
time will the X-ray set be energised, so there is no danger. After they
have made the measurement and returned the clip to its position, they can
get on with their work manufacturing the instrument. I would like to
discuss this with you further, but am on leave next week. We should talk
about it the following week, but it is important that Dennis' work not be
disrupted or held up in the mean time.
Regards,
Erich
