First Booster Extraction

A small 700Mev electron spot from the first screen in the Booster to Storage (BTS) ring transfer line.

On the night of 3/4 April 2006 the first electrons were extracted from the second of Diamond's three particle accelerators - the booster synchrotron - towards the main storage ring, taking Diamond one step closer to completion.

At the present 700MeV operating levels, we now have substantial charge at the Booster to Storage ring beam dump on the inner side of the booster wall. This extracted beam from the booster, using a pulsed magnet extract system, came on line Monday/ Tuesday night (3/4 April 2006). Booster beam on this 700MeV energy is ready for injection into the storage ring for preliminary tests.

 

The beam dump Faraday cup (blue trace) and the BTS1 Integrating current transformer (red trace).      This shows that about 50% of the beam injected          into the booster is reaching the beam stop.

Vince Kempson, Injection, Commissioning & Operations Manager at Diamond, says, "The  booster is now  ready  for   injection trials into the storage ring, at 700MeV. We are investigating temporary cooling additions while we await site main cooling so we can bring the booster energy up to 3GeV, the energy the electrons will have in the storage ring once Diamond is operational."
