keyword=OTR and InterferometerShown are the OTR and Interferometer with a 15 uA beam.
(Note the message that the current is low is due to the
fact EPICS is pointing to the wrong variable and is not
seeing any current)
The OTR is saturated (adding the filters didn't work as expected)
but both devices are seeing the beam size
as approx. 0.4 mm which is apporx. an energy spread of 1E-4. This
is about what we expect with the present inject setup which has
been optimized for G0. Tests have led accelerator to believe they
can deliver 2.5E-5 energy spread beam to Hall A along with deliving
G0 beam, but it has not been done for our present running conditions.
