Provide high-level scientific guidance and drive the physics program. PIs set the long-term physics goals and approach at the project level (many months) and on the week to week level. The PIs maintain an online document over the many months of the commissioning phase that is updated weekly with input from Scientific Coordinators, Lead Operators, and the whole CBETA team. The PIs coordinate the Friday 3pm collaboration meetings where results are disseminated and plans for the next week are made. The Cornell PM will use a section of this meeting to organize support for the upcoming shifts. PIs are responsible for building external collaborations with outside labs and issuing invitations to outside collaborators.

Beyond the regular PM responsibilities documented in CBETA's Project Management Plan, during commissioning the Cornell-PM (just referred to as PM below) has the following tasks. The collaboration meeting will be moved to Friday 3:00, the first part will be dedicated to discuss rung result, the second part to shift scheduling, covering scientific goals and personnel schedules. The PM will cover the weekly personnel organization in that meeting. The PM also acts as liaison with external collaborators and visitors that help with commissioning. He also helps CBETA-team members from BNL with their commissioning related arrangements. The PM is first point of contact if an operator cannot fill their shift, ensure that adequate shift staffing is available to meet commissioning needs, and tracks vacation and other absences for staff. The PM is responsible for safety regulations during commissioning, that all operators, staff, external collaborators, and visitors must follow. The PM arranges that CBETA team members, outside collaborators, and visitors get appointed appropriately into the CLASSE HR structure, allowing them access to Cornell facilities (i.e.: ID cards for building access) and the CU Learn safety tracking system. The PM assigns safety training requirements and ensures they are up to date. The PM provides reports and updates to the broader CLASSE community through the Tuesday resources meetings and via the CESR operations meeting.
Is responsible for coordinating TSEs for the technical components provided by BNL. For periods of time where a TSE from BNL is require in the control room, The B-PM will coordinate their visit with the C-PM.
Adam Bartnik is the L2 for commissioning. While he is also one of the lead operators, as L2 he has the additional responsibility (a) of training of new lead operators, (b) of maintaining the training documentation, (c) of administering the entry test for new support operators, (d) for setting administrative machine limits, (e) for seeking safety approval for these limits, (f) for adequate eLog documentation, (g) calling the daily shift-change meeting at 3:30, (h) give presentations on CBETA commissioning.
Scientific Coordinators are assigned to each scientific problem under analysis. They lay out the scientific plan for the time allotted to their commissioning task. Works with the PM to ensure the right people are in the control room to achieve that scientific program. Often present in the control room and provides continuity from shift to shift during that scientific program. This means that the SC would have a shift that overlaps the day and evening shifts, but may not be there for the entirety of both shifts. Most importantly sets the short time scale approaches to be followed by the operators.
The Scientific Coordinator may or may not be directly involved as lead or support operator. The SC can be from the CBETA team, or could also an external collaborator. The SC needs to have visitor status.
A lead operator is highly experienced at operating CBETA and is fully qualified for any CBETA operation. The lead operator has primary control over CBETA, their hands are on the knobs. They must be experienced in all aspects of debugging CBETA and its subsystems. The expectation is that LO requires extensive hands-on experience of many months to gain the background in the practical aspects of running CBETA.
Current Lead Operators (as of October 2018):
The support operator is a partner and in safety terms the second person to the LO. Typically the SO will provide operational support to the LO, and work under their general direction. There may be times were the SO has primary control of CBETA, or they may be focused on scripts, coding, improvements, or data analysis. Often they will be utilizing CBETA-V, the online model, to support the work of the LO. The training requirements for the SO are significantly lower than for the LO, but would include knowledge of most of CBETA subsystems. When two lead operators are shifted at the same time, one would serve as SO, though this distinction is not critical. The SO can be from the CBETA team, or be an external collaborator, as long as they have visitor status and have passed the SO training. The L2 for commissioning administers the SO acceptance exam.
Extensive work as an SO is the path to becoming a lead operator.
Technical experts on CBETA subsystem that may be required in the control room, but who are not directly running the accelerator. For example, RF or Cryo experts that are controlling subsystems during operations. They may be required during operations continuously, only for setup, or perhaps for a particular experiment. Hopefully their presence will diminish over time as the operation of their subsystem becomes automatic or integrated into the machine controls.
Examples: Robert Michnoff (BPM), Peter Quigley (RF), Dan Sabol (Cryogenics), Dwight Widger (Safety)
As part of the Cornell-Brookhaven collaboration, CBETA-team members from BNL can fill any role, provided they have received the associated training and examination. Some of the commissioning roles require a significant time commitment. It is estimated that regular control room experience is needed for several month before designation as an LO. However, SO or SC may only need several weeks of preparation and a BC might fill this role regularly.
An EC is from an institution that is not part of CBETA. They are at CBETA to perform CBETA driven research. Participation of ECs is coordinated by the PIs and scheduled by the PM. The EC could fill many of the roles above but would primarily be either the SC or SO during their visit.
A short visit by an EC would most likely be in the role of an SC, since they would not have time to become a SO. A longer visit of several weeks would be required to take on the role of an SO. Teams of ECs would be expected to provide people to fill multiple roles. It is expected that each EC would typically contribute several weeks of effort to the CBETA project. This time is considered the minimum to be trained and integrated into the CBETA operations without posing a drawback to operations.
EC may at times function in the role of TSE in situations where they bring pieces of equipment or instrumentation for testing, or they may support and contribute to the local TSE staff.
It is expected that ECs contribute sufficiently to be included in the author list of papers written on work performed during their visit.
Being a visitor is a status at CLASSE that one obtains by satisfying several safety and training requirements.
An observer does not participant in research or commissioning. They are welcome for networking reasons or to encourage them to become ECs in the future. Their primary role is to observe for their own benefit for a short period of time. Observers should be carefully considered and scheduled, since their participation can be a distraction in the control room. Typically the observers contribution would not rise to the level of being included on any papers.
