CLEAN ROOM FOR SCIENTIFIC DEPARTMENT OF NUCLEI
COLLISIONS
IN THE LHE JINR

• According to conceptual
  requirement, which is asserted to industrial
  sites destined for mass production of modern
  particle detectors, the presence a clean rooms of
  a high class of cleanness is obligatory in
  structure of these sites for such scaled
  experiments as ALICE, ATLAS, CMS. The realization
  of finishing operations, in particular, for
  assembly of wire chambers in conditions of "a
  clean room" is a necessary condition, which
  guarantees their high reliability and
  uninterrupted work during experiment.
• To ensure a fulfillment to these
  conditions the room of a high class of
  cleanliness satisfying to all necessary
  requirements was constructed in LHE within the
  framework of experiment ALICE (theme leader
  A.Vodopianov). The clean room was created by
  joint efforts of the collaborators from Nuclear
  Collisions Department LHE JINR and Research
  Centre of Applied Nuclear Physics Minatom of
  Russian Federation - the members of
  Collaboration. RCANP is leading organization on
  development track pore membranes and concerned
  products on their basis. It has wide experience
  in building of clean rooms for the various
  purposes - from rooms for assembly of detectors
  up to operation-room in various clinics in
  Moscow.
• The clean room was assembled from
  metal wall panels of "sandwich" type by the
  specialists who are possessing experience of
  realization of similar tasks, confirmed by the
  license for installation of clean rooms. The
  equipment and materials certified in the proper
  way were used for assembly of the room. Use of
  such materials, and subsequent certification of
  the room is a guarantee that parameters of
  climatic conditions inside a room will correspond
  to the requirements established in the technical
  design reports for detectors assembly during
  whole term of manufacture.

Room has working area 28 m2 and there is
two areas inside, from which a basic one - where
an detectors assembly take place, is central area
of 12 m2, that corresponds to a class 1000 of
cleanliness (less than 35 dust particles by the
size 0.5 microns per litre of air). Another one
is peripheral area by class 10000. The room
environment cleanness is provided by diffuse gas
exchanger based on track pore membranes and
filters for preliminary cleaning located in the
air preparation lodge. In the same place the
air-conditioner and noise-suppressor are
installed to ensure stable air temperature and
humidity modes and comfortable service
conditions. The access in the clean room for the
personnel occurs only through tambour, which
volume is cleaned during work as well. The
special clothes - service gownes, gloves, head
covers and footwears intended for realization in
the clean environment are used in the room.
The clean room can work in several modes. Basic
is an air circulating mode with air cleaning from
aerosols and submission 15 - 30 of external
fresh air. It allows to achieve the very high
level of air cleanness and to support it for a
long time. The maintenance of the room cleaning
and ventilation is completely automated and
allows smooth and exact adjustment of operation
modes of the room, according to parameters set of
air temperature and humidity. The erected
clean room is well-built-in in industrial site,
arranged around room. This advantage allows to
carry out a complete cycle of detectors
manufacture and testing inside the laboratory
building in stable air temperature and humidity
conditions without transportation of detectors on
long distances.
