Dear members or the Rietveld list,
I am sending this on behalf of colleagues in Africa. I have invited them
to join the list themselves. Below is their request.
We are a solar energy materials group at the Masinde Muliro University of
Science and Technology (MMUST) situated in the western part of Nairobi in
Kenya. We have a powder diffractometer in our lab that is currently not
functioning and we were wondering whether anyone on the list might have
some experience and could offer advice or help.
The details of the instrument are:
Company name: Angstrom advanced Inc.
ADX-2700 X-RAY DIFFRACTOMETER
MODEL: ADX-2700
SERIAL NUMBER: XTDS-228765
BUILD DATE: 7/2/2015
Basically the issue is it turns on, but Software in the interfaced computer
does not communicate with the main XRD machine.
The diffractometer turns on well but has never worked since 2017 when it
was bought. Since it cannot communicate with the software, it does not work
in its current situation in principle. The machine was diagnosed in 2018
with the suggestion that the motherboard may have been damaged by rodents.
We do not have any maintenance contract (nor any funds to support one).
If anyone has any advice or help to try to get it going we would be very
grateful.

Patrick Tonui (Physics Lecturer), Henry Wafula Barasa (Physics Senior
Lecturer), Boniface Ndinya (Associate Professor) Maxwell Mageto (Senior
lecturer and Chair Department Physics).
PS, we also have a similar issue with an SEM from the same manufacturer in
case anyone can help with that too: The SEM turns on well but does not work
too. Initially it was diagnosed to lack filaments.
