HIGH  RADIATION  TO  MATERIALS  PROJECT  –    T1  DISMANTLING  &  TI2  BEAM  LINE

The HiRadMat Facility

LMC, July 7,2010

2

  A  new  facility  being  built  to  study  the  impact  of  intense  pulsed  beams  on  materials  

  It  is  located  in  the  TCC6/TNC  area  (ex-­‐WANF  tunnel)  and  will  use  an  LHC-­‐type  extracted  beam  from  SPS  branching-­‐off  the  TI2  line  in  the  TT60  tunnel.    

  HiRadMat  will  be  an  test  bed,  important  for  the  design  validaLon  of  LHC  near-­‐beam  components  before  installaLon  in  the  machine    LHC  collimators,  machine  components,  material  studies  (bulk,  superconductors),  beam  windows,  vacuum  equipment,  etc…  

What is it?

5   The  dismantling  of  the  T1  target  staLon  (target  +  MTR  magnets  from  old  west  area  beams  +  

shielding)  is  necessary    to  allow  installaLon  of  the  TT66  beam  line  magnets    for  later  intervenLons/maintenance  of  TT66  and  TI2  beam  lines    for  radiaLon  protecLon  (ALARA)  and  general  policy  to  remove  obsolete  installaLons  from  the  operaLonal  

tunnels    

  So  far  a  good  fracLon  of  the  shielding  blocks  &  equipment  has  been  removed  

  The  removal  of  the  two  MTR  magnets  is  the  next  step,  which  requires  dismantling  of  ~30m  of  beam  vacuum  (and  one  quad)  of  TI2  line.    

Dismantling steps

  We  would  like  to  profit  from  the  next  technical  stop  on  week-­‐29  to  do  this  operaRon  

  All  groups  contacted  and  will  be  available    Actual  intervenLon  for  the  MTR  removal  ~1day    End  of  the  works  scheduled  for  Wednesday  

12:00PM    The  TI2  beam  line  will  be  back  in  operaRon  on  

Thursday,  well  on  Rme  for  the  LHC  restart

  All  handling  material  available    

  Tested  on  a  spare  magnet  and  with  real  condiLons  (slope)  

  OperaLonal  procedures  and  safety  issues  being  discussed  

  The  magnets  will  be  moved  to  TT61/TT4  for  storage  as  spares

9 Schedule

  Schedule  confirmed  by  all  groups  involved    Thanks  to  a  new  sector  valve  installed  earlier  the  vacuum  sector  is  ~50-­‐60m  and  addiLonal  

pumping  can  be  installed  should  need  be  

  The  removal  of  the  remaining  shielding  blocks  and  T1  target  can  be  done  without  interfering  with  the  TI2  beam  line  

  The  cleanup  of  TCC6  is  an  important  step  to  maintain  the  HiRadMat  schedule  on  track
