VEPP-2000 running in Round Beam mode

Submitted by dshwartz on Sat, 12/17/2016 - 19:17

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.

Hiroshi Amano @ VEPP-2000

Hiroshi Amano, Nobel Prize winner in physics for the blue light-emitting diodes (2014), visited VEPP-2000 collider during excursion over BINP facilities.

Booster BEP and transfer channels progress

Submitted by dshwartz on Sat, 04/25/2015 - 02:08

First modified BEP "small" D-quad has been delivered from BINP workshop and immediately gone through magnetic measurements tests. The field-current dependence showed good accordance with predictions.
The assembling of lower part (in tunnel) of beams transfer channel K-500 from BINP Injection Complex is finished.

VEPP-2000 ring is finally assembled and ready for action

Submitted by dshwartz on Tue, 04/07/2015 - 01:26

All modifications of VEPP-2000 storage ring itself are finished. These changes include: two new dipoles' vacuum chambers with additional inflectors; new mirrors for synchrotron radiation output for beam diagnostics; second screper near CMD-3; repair of solenoid with protective vacuum leakage. Vacuum system is assembled, RF cavity is baked. All magnetic elements are mounted and aligned. Storage ring is ready to accept beams except for the absence of transfer channels and disassembled booster synchrotron.
