Overview

Accelerator equipment relevant for the control system is organized in groups. The Data Master of the timing system generates command messages for groups, but not for individual equipment. The equipment within a group belongs together conceptually. An example of a group might a ring machine. The ordering of equipment into groups is defined by the way the accelerator complex is operated. With the new timing system, the group ID is analogous to a machine ID.

In principle, the ordering of equipment into groups depends on the role of the equipment for the production of a specific beam. There are two schools of thought.

CCT (Controls Coordination)
  • A group is a collection of equipment that always belongs together.
  • A specific equipment may only be member of one group.
  • A specific equipment always belongs to the same group (that assignment to a group does not depend on a beam).
  • Many groups (> 200) are required for the operation of the machine.

Timing Team
  • What belongs together happens together.
  • A specific equipment may be member of more than one group.
  • When the operational concept of the machine is changed, new groups can be introduced and specific equipment can join another group too.
  • The number of existing groups may be large
  • The number of groups for the production of specific beams is small.

As the view of the CCT can be seen as a special case for the more general view by the Timing Team. Both concepts can coexist, as long as the principle what belongs together happens together is not broken. This implies, that a timing receiver node must not (never!) be configured for more than one group at a time. In the long term, a migration to the concept of the Timing Team is possible. Then, a timing receiver node can be configured for many groups at the same time.

Group IDs

A group ID has 12 bit. This is divided into two ranges
  • 0d0000..0d1023 (0x000-0x3ff): operative, assignment by CCT
  • 0d1024..0d4095 (0x400-0xfff): reserved, assignment by TOS



groups.png
Fig 1: Timing Groups. Shown are rings (yellow), electron coolers (blue), ion sources (orange), UNILAC sections (magenta), intersections (grey) and targets (green). A timing group (solid arrow) is named using the scheme origin_TO_destination, see table below. The group ID GID is given in decimal and hex on the right side of an arrow (rings, electron coolers: inside box). Dashed arrows are used to guide the eye and do not represent timing groups. Boxes with dark green (pink) borders denote accelerators (TVS and NE areas), but the assignment of nodes to accelerators might not be correct for all cases.
