Hi Eric,
Yes, the timing is very unfortunate. We really need to get the tracker serviced going in to the dark period though - better for everyone.
Mohan approved both trackers in this case - the one Brian is using was purchased exclusively for beamline alignment.
I have an idea going forward that will benefit everyone.
We have a Leica AT930 tracker that was purchased by the upgrade. It does not have built-in WiFi, but can connect through a router.
We are currently using it for IDVC alignment in 981, but this work is nearly complete. We connect to it through a LAN cable.
In your case, the instrument will be set up in a semi-permanent location and will not need a Wifi connection.
The AT 930 lends itself better to your application. The AT 403 on the other hand is a superior surveying instrument and
is better for our beamline alignment activities.
The insertion device vacuum chambers are nearly complete. The AT 930 should be available around the time
our instrument is returned.
I think it will be a good trade... let's discuss further.
Kind regards,
Bill

To clarify, the AT403 is better for our application because of its portability and ease of setup. We will
be in every single hutch in the experiment hall over the next year or more, and having the lightweight
instrument will make our operations more efficient.
The AT903 is a heavier, more robust instrument that is more complicated to set up. It has the same
accuracy as the AT403, and includes both an absolute distance meter (time of flight) and a laser
interferometer with a much higher sampling rate. The tracking is much smoother.
The cost difference is significant. The AT930 was ~$130K; the AT403 was ~$80K.
I think the trade would be mutually beneficial.

Thank you Bill,
one more technical point, the AT903 is a few years older. How often do these need to be repaired for laser head, etc... ?
I've added Suresh in the CC field. I'll get back to you with a response to your trade proposal.

Hi Eric,
These instruments are rather robust; I would expect 10 years of service. The instrument we would
like to trade is ~5 years old, but has not seen as much service as our newer ones because of the lack
of WiFi connectivity.
An advantage to developing the process using the AT930 is that at the end of the upgrade project we
will have excess trackers. These will be AT930's that can be used for detector positioning. We do not
want to give up the AT403's.

Hi Bill,
just wanted to acknowledge that you delivered the Leica AT930 to us and gave us a quick demo
this morning. The unit is SN 750529. I am happy that we can help make your job a tiny bit easier
with the more mobile unit that was purchased for 8-ID-E.
Thanks again,
Eric |
