Hi


We are planning to test SHMS Dipole this morning.

Initial tests to 1300 Amps to confirm condition and operability.

This is very low impact and at 1300 Amps we are below the threshold for 
the fast dump initiated quench back and subsequent high pressure and 
high gas flow into warm return.

If these tests go OK we will request a higher current limit up to about 
2000 Amps .

This is still below the threshold for quench back.

Success means SHMS can do optics tests using the 3 pass beam.

Testing will begin about 0900 and continue to about 1200.


Cheers


Paul
