Things that I am working on

Ground motion studies for the Tevatron and future accelerators

Permanent Magnet R&D at Fermilab

and

The MuCool beam line at Fermilab

Ground motion projects and data

As part of R&D for future accelerators a Hydrostatic water level system has been installed in a dolomite mine near Fermilab and in the MINOS near hall at Fermilab. Both are in the Galena Platteville dolomite. A data base has been setup every month data is added. Currently there are data for MINOS from December 1 2005 through Oct 30, 2011 and data from the Lafrage mine from September 1st 2006 until Oct 25, 2011. February of 2010 a system of 6 Budker sensors were installed in the 2000 ft level of the Homestake mine these data are being added to the data base. In June of 2011 12 Ultra Sonic HLS sensors were installed on the 4850 ft level. The data is also in the data base.
There is a list of all my logbook entries on these systems I will try to keep this up to date.
In January of 2009 I went to Lead South Dakota to help with installation of a HLS in the Homestake gold mine. The mine is flooded and there is a desire to monitor ground motion as the water is removed in preparation for the Deep Underground Science and Engineering Lab (DUSEL). There are pictures of the installation and data available.
As part of my water level work I have set up a test of several different sensors. Pictures and data are available.
I am preparing a paper on HLS systems in use at Fermilab and DUSEL. This is a work in progress this is the link to the paper and the figures.
September 11th 2012 the IWAA will be held at Fermilab and I will present a paper on the status of all HLS systems at that time.

Permanent Magnet Work

Fermilab and the Spalation Neutron Source (SNS) at Oakridge National Lab are colaborating on an novel ion stripping scheme using a permanent magnet to strip the electrons from hydrogen. The RFP, revised drawings and more details are avialble.

Mu Cool and the MTA beam line

The Muon Cooling experiment at Fermilab is a series of test to see if it is possible to reduce the momentun spread of muons. There is a 400 MeV beam line off of the LINAC at Fermilab that brings H- into the experimental hall. There are some pictures of the beam line avaiable. Also there is a job list of things that need to be done.

There is a need to re train the Mu Cool Solenoid to get to 5 Tesla. Here is a link to get to some information on that work.
