Introduction
Since the previous EATM meeting two PBC events relevant for
EATM have taken place:
• A meeting of the Conventional Beams working group on
February 22nd
This was a very useful and interesting meeting where all groups
updated and refined their requests for beam and infrastructure
• A plenary PBC meeting on March 1st and 2nd.
Again a very interesting meeting, with summaries of the
experiments (physics cases) and reports from all accelerator
working groups. EATM is mainly concerned with CB, but also at a
lower level with BDF and later possibly AWAKE.

Conventional Beams WG
Under consideration at present are:
• NA62:
Proposal to operate in beam-dump mode
• NA64++:
High intensity electron, muon and hadron beams for dark particles searches
• KLEVER:
High intensity KL beam (high flux, pencil beam, new target) for rare decays
• COMPASS++: RF separated beams for hadron structure and spectroscopy
• Mu-e:
150 GeV m beams for high preicion hadron vacuum polarisation for g(mu)
• DIRAC++:
DIRAC@SPS for high statistic mesonic atoms
• NA60++:
Heavy ion beams for dimuon physics
• NA61++:
Higher intensity ion beam for charm studies

CBWG Kick-Off Agenda

Conventional Beams WG strategy
During the kickoff workshop a large number of fixed target
proposals were presented. It is important to perform preproposal studies in order to allow the PBC committee and
concerned working groups to progress with their evaluation.
Given the relatively long list of studies, we were asked to first
focus on those leading to a possible short and medium timescale implementation and requiring only limited resources for
their implementation. Additional studies will be performed
based on the information provided by the collaborations and the
following criteria:
- according to the analysis of the physics WG
- where sufficient details are known required for an implementation study
- where a study can be performed within the timescale of the European
Strategy update.

Resources and Time line
• The PBC deadline is end of 2018 / beginning 2019, in time to provide
input for the European strategy decision.
• The first priority of the studies is to clarify the technical feasibility and
complexity of the various considered proposals.
• Another important part of the study is to evaluate the expected time
line and resource requirements for the proposed experiments.
• Ideally, feedback can also be provided how various proposals could
be effectively combined or scheduled in order to allow for an
optimized use of the experimental areas in line with beam availabilities.
• It’s important to note that the timeline of the requested studies is also
correlated with the required respective resources and their time profile.
• for this additional resources are needed
(and must in most cases be trained) .

Next steps:
• Membership and chairs of CBWG sub-groups being defined.
• So far rather a request from PBC to study all proposals rather than a
clear prioritisation, although more emphasis was given to the BSM
experiments than to the QCD related ones.
• First requests for extra resources have been submitted to PBC chairs
• In-depth studies shall start very soon.

Identified Test Beam Studies
• KLEVER has a conceptual design of a KL beam involving a crystal
based photon converter. Its effect on the KL beam can be
significantly reduced by using a crystalline converter, aligned with the
beam.
• To test and validate the concept, a test with a tagged photon
beam is considered, as well as at a later stage a possible test with
a neutral kaon beam in the K12 line.
• Other experiments may require test beams as well:
• a prominent example in the BDF working group is SHiP.
• or target test requirement for m-e
• Test beams may also require discussions in this WG, in particular
if the test beam implies non-standard requirements.
