The ABS Project

The ABS project

• Objective Implement Automated Beam Steering and
  shaping Methods for accelerator operation
• OPEN project
• Annual project planning sets targets and
  milestones
• Tasks and targets discussed in topical Monthly
  meetings

3
PS ABS recipe

• Based on the nominal optics a linear correction
  Matrix A is created using the first order terms.
• The errors at the available Monitors are
  measured, each measurement is represented by an
  error vector b.
• The universal solver Micado is applied to return
  the correction vector x such as the norm of the
  residual vector
• r A x b
• is minimum after iteration over the number of
  correctors.

ABS 1997

• Software Analyses
• Database
• Application program
• Studies
• Matching
• Linac-PSB
• PSB-PS
• PSB four rings
• Bump42
• PSB Orbit

6
Why do we put such an effort on the database?

• Experience with the test programs has shown that
  the weakest point is the generation of Matrices !
• Generic ABS program is DATADRIVEN
• The data must be MAINTAINABLE

7
Database for ABS application program

• Database must handle
• PPM
• Multi function magnets
• Common elements for several PSB rings
• Database objectives
• Maintainable
• Avoid duplication of data
• Easy access to other databases
• PS control database
• Survey database
• Other CERN optics databases
• Evolution potential
• General machine documentation
• Interconnection with application programs
• Portable

8
What does ABS need from database

• Complete listing of all Magnetic elements and
  Monitors belonging to each existing type of
  machine operation
• Nominal optics
• Nominal position along the beam-line
• Magnetic length
• Edge-up and Edge down
• Calibration points

Data entry form
10
Data interrogation via ACCIS WEB browser

• Click and you see it!
• AND
• WEB pages are dynamically created from the
  database using the ORACLE WebServer

11
Generic application program

• Data-driven
• Portable
• Common look for the different machines and
  transfer lines, and for the different types of
  corrections for which it applies
• Interface to different instrumentation devices
• For calculation s, the program uses the
  Mathematica package BeamOptics.
