GlueX Endorsed Experiments

D Acquiring Data and Endorsing Experimental Proposals

While the initial period of beam in Hall D will be dedicated to commissioning and running with the the base Hall D equipment, it is expected that additional experimental proposals for Hall D beyond the primary GlueX physics program will be made. Additional proposed experiments in Hall D which use any portion of the GlueX detector equipment may seek the endorsement of the GlueX Collaboration.

D.1 GlueX Collaboration Endorsement

1. GlueX-endorsed experiments are recognized as distinct experimental directions being pursued under the organization of the GlueX Collaboration.
2. The endorsement of the Collaboration implies a commitment of the entire Collaboration to operate detector equipment, staff shifts, and calibrate and process the data collected.
3. All proponents of such proposed experiments must be members of the GlueX Collaboration, or have a plan approved by the EG and CB for joining the Collaboration and participating in ongoing GlueX experiments.
4. All Hall D experiments which were approved by the PAC before 2018 are considered to have the endorsement of the GlueX Collaboration.

D.2 Experimental Proposal Endorsement Process

1. The experimental proposal endorsement process should begin with a discussion between the GlueX Spokesperson, Hall D leader, and proposal proponents, and may include a presentation to the Collaboration.
2. The proponents are expected to prepare a document which describes the necessary modifications to configuration of equipment, needed running time, and expected physics impact. This document is referred to as "the proposal" in the bylaws that follow. The responsibilities of member groups for detector operation and calibration should be clearly specified. This information must be presented to the Collaboration, either at a Collaboration Meeting or at a meeting of the Physics Working Group.
3. The evaluation of the technical feasibility and physics merit of the proposed experiments will be coordinated by the Collaboration Board, in consultation with the Hall D Leader. The CB will be responsible for designating at least one and no more than three internal reviewers for each proposal.
4. The internal reviewers should receive a draft of the proposal to review no later than 90 days before an eventual vote by the collaboration. The reviewers are expected to interact with the proponents of the proposed experiment and may request revisions or additions to the proposal in order to complete their review.
5. After review, the committee will prepare a written response to the charge of the CB that includes a recommendation on whether the proposal is appropriate to be considered for endorsement by the Collaboration. The evaluation of appropriateness should be based on a variety of factors including technical feasibility, physics merit, completeness of the proposal as well as considerations of the schedule and required commitment of the Collaboration. The committee report will be communicated to the proposal proponents and be made available, along with the proposal, to the members of the Collaboration. The EG and CB shall then decide if the proposal will be put up for a vote, which should be initiated no less than 30 days from this decision.
6. The proposal must be approved by a vote of two-thirds of the Collaboration.
7. In exceptional cases, a proposal may be put up for a vote at any time by the GlueX Spokesperson and Hall D Leader.
8. If a proposal is not put up for a vote or does not pass the vote for endorsement, the proponents may revise and resubmit their proposal for consideration.

D.3 Access to Data

1. Data taken during any run period or detector configuration of a GlueX-approved experiment may be analyzed by any member of the GlueX Collaboration.
2. Members of the Collaboration shall inform the Physics Analysis Coordinator of their intent to analyze data in order to maximize efficiency.
