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

Submitted by dshwartz on Wed, 07/12/2017 - 01:45

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.

VEPP-2000 running in Round Beam mode

During summer shutdown further modifications of BEP were done. Two modern pickups were installed. Two copper mirrors for synchrotron radiation based beam diagnostics were changed due to insufficient quality. The new SR outlet for future material science experiments was equiped with movable water cooled absorber. At the end of the K-500 tunnel the Faraday cup was installed for absolute beam charge measurements.

Electron beam back @ VEPP-2000.

Since the beginning of the year we were working hardly to bring the beam from booster synchrotron BEP to VEPP-2000 storage ring. Transportation channels with new dipoles capable to work @ 1 GeV were assembled and aligned precisely. The beam step-by-step moved through the beamline controled @ two types of BPMs.

First beam @ BEP!

Great news! First electron beam captured into upgraded booster BEP. Synchrotron light of tiny beam is visible by CCD or naked eye.

Towards beam arrival

In September all the BEP quads were coupled into doublets, precisely aligned and doweled. In October the magnetic system was assembled at the booster hall and geodesicaly aligned. The vasuum system assembly started. In parallel the K-500 transfer channel was finished. The vacuum was obtained in the middle of December.

Magnetic measurements @ BEP are finished

Submitted by dshwartz on Mon, 08/10/2015 - 18:27

All the magnetic elements of BEP storage ring (12 dipoles, 12 "large" + 12 "small" quads) are finally passed through magnetic measurements. The last portion of "small" D-quads was measured by rotating coils in july. The difference within each family of magnets as well as the deviation between exitation curves of different multipoles lies inside the capability of corrector coils.

K-500 assembly approaches to completion

Submitted by dshwartz on Mon, 06/08/2015 - 19:31

Final part of K-500 e+e- beams transportation channel from new injection complex to VEPP-2000 complex is near to completion. In the BEP hall all K-500 magnetic elements are installed. The vacuum system assembly of the rising section is in progress.
