CERN’s LHCb experiment has donated its decommissioned outer tracker detector component to PANDA. 

PANDA is happy about a gift it has received from LHCb, one of the four big CERN experiments at the Large Hadron Collider. LHCb has sent their decommissioned Outer Tracker (OT) from Geneva to Darmstadt, where it has arrived at GSI (25. August 2023) after a special transport of five days via truck and ship. The LHCb colleagues at CERN prepared the detector in its transport frame with protecting plastic for a journey in three stages, due to the "package" size: Seven meter long, 3.5 meter wide, 5.5 meter high and a weight of 24 tons. The first stage of the journey by truck brought the OT from CERN to the harbour of Colmar where a Rhine ship took over the second stage and delivered the OT to Gernsheim harbour, where a truck did the last stage to GSI. 

The donation from LHCb to PANDA was initiated by by our deputy technical coordinator Anastasios "Tassos" Belias and Niels Tuning from LHCb/CERN after discussions about spare detector modules at a conference a few years ago.
Finally the LHCb collaboration decided to donate the whole OT to the PANDA collaboration, which was then formally signed in a contract between GSI and CERN/LHCb last year.

The donation was made possible thanks to the close cooperation in logistics and technical aspects between several colleagues at CERN and GSI/FAIR, in particular Niels Tuning (LHCb, Nikhef/CERN) and Anastasios Belias (PANDA, GSI/FAIR) and their relentless efforts to give the formidable outer tracker a second life. The donation was kindly agreed upon by the LHCb groups who meticulously built and operated the outer tracker, namely,

•  the National Institute for Subatomic Physics, Nikhef, the Netherlands,
•  the Physikalisches Institut der Universität Heidelberg, Germany,
•  the National Centre for Nuclear Research, Warsaw, Poland,
•  the Henryk Niewodniczanski Institute of Nuclear Physics, Polish Academy of Sciences, Krakow, Poland,
•  and the Technische Universität Dortmund, Germany.

The OT consists of 54.000 Straw tubes, each 2.4 m long with a diameter of 5 mm, which are arranged in staggered double layers and mounted to twelve C-shaped mechanical frames. The C-frames are inserted in the big blue transport frame (c.f. pictures).  

There are several ideas how individual parts of the OT can be re-used in different experiments and set-ups in the future.
At PANDA the tracker will be able to detect the light hadrons produced by the collisions. Hadron spectroscopy is where the physics goals of LHCb and PANDA overlap, and the two will be able to collect complementary data that can later be analysed and compared. The tracker will also be used by students and young researchers in R&D projects, as well as in outreach activities for schools and the general public.

Every year, PANDA awards a prize for the best PhD thesis in PANDA of the last year and we’d like to ask again for nominations for this year's prize. The rules are simple as usual:

Who is eligible? And how can nominations be made?

Members of PANDA who have had the oral defense of their PhD thesis during the year preceding the selection are eligible. The thesis may contain work related to other topics/experiments, but the majority of the work in the thesis must be directly connected to PANDA. The thesis advisor can nominate someone who successfully passed the oral defense during the period from June 1, 2022 to May 31, 2023.

A nomination can be made until August 31, 2023 (almost 2 months from now!!) by submitting the following information to the speaker of the collaboration:

1. A nomination letter in which the content of the thesis and the importance of this work for PANDA is described. This should also motivate why that thesis should be considered as the best one of the selection period from PANDA.

2. The thesis must be made available online on the PANDA webpage, and the URL must be included in the nomination. If it is not allowed to upload the thesis to the PANDA website, then a hard copy of the thesis must be submitted.

3. If the thesis is not written in English, then a (couple page) summary must be provided in English.

4. A copy of a certificate showing the grade achieved by the thesis (and a short description of the grade scale). This certificate should indicate the date of the oral exam. If that is not the case, then some other confirmation of when the oral exam was held must be provided (a letter for the thesis advisor will suffice, if a copy of a formal document is delivered before the September meeting.)

The nomination must be made in writing/email. The PANDA Award Committee will propose a PhD Prize Committee as soon as all nominations are in. 

Please keep in mind that potential awardees for the PhD Prize need to be present at the GSI Meeting in October for their PhD presentation. Please consider registration and (if necessary) visa application in time for them.
