Here, you can find information relative to the beamtime
planning at PHELIX. In case of questions, please email:

Applying for beamtime
PHELIX is a user-oriented facility. Anybody can apply for access to the facility
to conduct experiments. Calls for proposal are done on a regular basis, at least once a year.
Users are invited to register to the
GSI user group page to be
automatically informed about proposal submission deadlines.

Proposal review and experiment scheduling
Proposals are evaluated by the
GSI advisory commitee.
There are several possibilities for users.
- Submission can be made to the PHELIX and Plasma Physics Advisory Commitee
(PPAC).
This is particularly true for laser only experiments.
- For European users, submitting your proposal to Laserlab in addition to the PPAC
may help with the cost of the experiments.
- Other proposal outside the plasma physics area, e.g. in atomic physics,
can be submitted to other advisory commitees of GSI
(G-PAC).
Once a proposal is approved, the principal investigator is personnally informed and
he should contact the laser team to schedule his beamtime.
The experiment design review
Because experiments driven by PHELIX require a close work between the laser team
and the experimental team, the PI is requested to present an experiment design review,
at least two months before his beamtime. The beamtime will only be scheduled after a
sucessful experiment design review has been presented. The guideline for preparing
the design review can be downloaded
here.
These are some of the points that must be covered during the review:
- Statement about the goals. The goals of the beamtime must be stated.
The laser team verifies that the goals are in line with the proposal.
- Experiment layout. The PI is invited to show that his experimental
setup matches the capabilities of the PHELIX target areas. For this, drawings of the
different target areas can be requested in DXF or STEP format. A PDF view of the PLH
chamber is available here
- Shot plan. The number of shots delivered by PHELIX is about 30/week of
beamtime. The PI must state how he intends to use these shots. In addition,
the types of targets to be used must be
communicated because different targets imply different levels of risk for the machine.
- Safety regulations of GSI must be followed. In particular, the
shielding plan against radiation must be presented.

During your beamtime at PHELIX
The following is a list of the key protagonists which interact before and during the experiment.
It also states their duties
- Principal Investigator (PI): this is the person who submitted the proposal.
His main duty is to organize the experiment design review. This means:
- to prepare and hold a conceptual design report/review at least 2 months before the
experiment starts,
- to write and distributes the review minutes,
- to prepare the list people participating to the experiment and communicating it to
the GSI.
- GSI Contact Person: this person is someone who has already experience with PHELIX.
In most case, it will be an employee of GSI or from the neighboring universities.
His task is to tackle issues on a technical design side. In particular, he should be able
to communicate with the PHELIX team to define the experimental parameters and laser
configuration.
- The GSI Contact Person is aware of the GSI policy regarding radiation safety.
He will seek approval of the safety department of GSI SiSt before the experiment starts.
- The experiment coordinator (EC). This person implements the experiment and executes
the experiment plan alone or with the experimental team. His duties are the following:
- The EC must plan to meet with the shot director (SD) at the beginning of every shift to discuss
the shot plan for the day.
- The EC is responsible for coordinating the activities of the experimental staff.
- The EC orders the shots from the laser. Nobody else is allowed to do so.
- The EC meets with the laser team everyday before the beamtime to communicate on the
shot plan for the day.
In general ECs cannot do two or more shifts in a row.
An EC must also be capable of making decision concerning the experiment during his shift.
- The shot director (SD). The shot director is organizing the shot sequence from
the laser side in coordination with the EC. He can be reached at extension x2000 at any time
during the beamtime. Shot directors are changed at every shift.
- Target area responsible person: This person supports target area relevant work
and provides local instructions regarding operation and safety.
- Abel Blacevic @ Z6
- S. Götte @ Laserbay
- T. Kühl @ Laserlab
