DAΦNE the Frascati F-factory, started the two beams
commissioning on March 1998. Since then a relevant
amount of experience concerning the techniques and procedures
for optimizing the luminosity has been acquired.
All the schemes used are strongly based on the use of
various diagnostic systems including a dedicated luminosity
monitor, orbit measurement, tune monitor, synchrotron
light monitor and others. A summary of the used
techniques, with accent on the diagnostic aspects, is
presented.

Injection efficiency, beam optic matching and
emittance preservation are very important parameters in
achieving a high luminosity in large proton
accelerators. We improved the analysing system of the
phosphor screen readout of the proton transport lines in
the accelerator chain of HERA with respect to the
parameters above. The screens are read out by simple
CCD video cameras. The signals are stored in local
frame grabbers. An analogue output of the stored image
is multiplexed and read-out by a fast PCI frame grabber
card in a PC. The beam orbit and the beam emittance
can be measured from each screen. A Visual Basic
program is used to displays the trajectory and the
envelope of the beam from a single transfer. The same
program helps to drive bumps to achieve a proper
steering through the line. The beam width can be
measured from selected screens to calculate the
emittance and other beam parameters including their
errors. The read out and analysing system will be
described and measurements will be shown.
