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.

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.

BEP-VEPP transfer channel assembling started

Submitted by dshwartz on Sun, 03/22/2015 - 22:36

The assembling of BEP-VEPP2000 beam transfer channels started. First "long blue" dipoles of electron beam channel were mounted and aligned geodesically. Another work - magnetic measurements of 12 BEP F-quads - was finished. All magnets shown good accordance of the field distribution to the corresponding calculations results. The saturation curves also agree well with prediction.

BEP quadrupole magnets returns from workshops

Submitted by dshwartz on Fri, 02/20/2015 - 21:07

   BEP quads began to return from BINP workshops. The magnetic measurements with rotating coils were started.
   All steering coils were finally installed into BEP dipoles. Dipoles are installed and aligned at the ring.
   CMD-3 detector has tested it's solenoid, magnetic field of 13 kGs was obtained. VEPP-2000 final focusing solenoids shifts were observed and measured.

Завершены магнитные измерения диполей БЭП

Submitted by dshwartz on Sun, 12/28/2014 - 20:33

Закончены магнитные измерения всех 12 диполей БЭП. Измеренное поле несколько отличается от расчётного, но удовлетворяет требованиям, необходимым для работы бустера. Измеренные магниты с установленной на ярмо магнитопровода катушкой коррекции устанавливаются на свои законные места.

КМД-3 готовится заехать на кольцо ВЭПП-2000.

Submitted by dshwartz on Tue, 11/18/2014 - 13:08

Криогенный Магнитный Детектор (КМД-3), один из двух детекторов на ВЭПП-2000, который был выкачен с кольца в сторону для ремонта на время модернизации комплекса, готовится занять вновь своё место на коллайдере. Эта сложная процедура включает в себя подвешивание соленоидов финального фокуса, стыковку их вакуумных камер с дрейфовой камерой детектора, и вкатывание по рельсам этой развесистой системы с последующей прецизионной выставкой магнитных элементов на своих подставках.

Зеркала вывода СИ на ВЭПП-2000

Submitted by dshwartz on Mon, 11/10/2014 - 18:57

Закончена замена зеркал вывода синхротронного излучения (видимой части, для нужд диагностики) из вакуумных камер всех 8 дипольных магнитов кольца ВЭПП-2000. Старые зеркала, в которых не удалось обеспечить хороший тепловой контакт между зеркальными пластинками и медной призмой, заменены на цельную медную призму с зеркальными поверхностями. Готовимся принять пучковые токи 200х200мА на энергии 1 ГэВ.
