Decelerating beams: first ever at the complex

Submitted by dshwartz on Thu, 12/21/2017 - 01:23

The new experimental run of VEPP-2000 complex started in November. In contrast to previous high energy scan, current data taking (experiment RHO2017) is dedicated to energy region below 500 MeV per beam. Started at Phi-meson the scan is currently moved below 390 MeV. It is the energy level of the beams provided by new BINP Injection Comlex. It means that for top-up injection to VEPP-2000 collider the beams now are decelerating at our booster synchrotron BEP, for the first time at the VEPP-2/2M/2000 complex!

Run 2016/2017 is over

The fruitful run 2016/2017 is finished. The data was collected in the energy range of 640-1003.5 MeV per beam (experiment 'HIGH2017'). The total integrated luminosity amounts to 53 pbn-1 per each detector, that is comparable to the data collected during three runs 2010-2013, and exceeds the total data collected by several generations of detectors at VEPP-2M (predessor of VEPP-2000). These excellent results were achieved due to usage of new powerful BINP Injection Complex and of course due to hard work of skilled VEPP-2000 team.

Above the design top energy!

The run 2016/2017 is going on. Both detectors are taking data while VEPP-2000 is moving step by step from the 850 MeV/beam energy level to it's top limit. The experimental program was suddenly expanded with request to collect some data @ 2007MeV at c.m., that corresponds to D0*-meson mass. Today this energy was surprisingly achieved and even surpassed. The Compton Back Scattering beam energy measurement system fixed the moment of energy tuning with 1005 MeV per beam value.
