Status of the JEM-EUSO collaboration Institut f. Astronomie u. Astrophysik Status of the JEM-EUSO collaboration Today we start to explore the extragalactic sky, beginning from the most obvious object, the Milky Way, that is the Galaxy in which we live. Andrea Santangelo* * Global Coordinator of the JEM-EUSO Collaboration JEM-EUSO simulation and analysis meeting, Toulouse 02.10.2014.

The JEM EUSO Collaboration Japan, USA, Korea, Mexico, Russia, Algeria Europe: Bulgaria, France, Germany, Italy, Poland, Romania, Slovakia, Spain, Switzerland, Sweden 16 Countries, about 80 Institutions, more than 285 researchers RIKEN, Japan: leading institution The JEM-EUSO collaboration

On behalf of the JEM EUSO Collaboration Thanks to the CNES… Thanks to the EUSO Balloon team… … and thanks to Peter and Guillaume! After so many years of study and lab activity, after so many words (document list)… this is the first time that we have data… this is a great opportunity.

Enlarge our international collaboration (3) Romenia: PI Dr. Eugeniu M. Popescu Participation to simulation with ESAF, other activities to be explored. Two Labs: High Energy Astrophysics and Advanced Technology Group Cosmology and Astroparticle Physics

Potential Contributions (II) Simulations (simulation working group): Shower formation and reconstruction (Germany) Radiation Transport in the atmosphere and atmospheric effect Clouds, Aerosols (Switzerland, Spain) Ultra High Energy Photon Simulation and Reconstruction (Germany, Mexico) Spatio-temporal exploration of satellite images and data mining in existing data archive and validation of data In-situ vs. Satellites Data (Italy, US) Lidar Simulations (Switzerland)

A new potential country: Belgium We have started discussion with the Universities of Liege (J. R. Cudell) and Gent (A. Meli) The idea is to join JEM-EUSO in the context of the recently formed Belgian Cosmoparticle Network Yesterday kick-off meeting in Liege at the Liege Space Center (CSL) to evaluate interest in hardware. The funding scheme will be similar to Switzerland. Important: expertise on Optics (both reflective and refractive).

Pathfinders: EUSO-TA TA site, UTAH, Black Mesa EUSO-TA: Cross-Calibration tests at the Telescope Array site in Utah in collaboration with the ICRR in Tokyo and the TA collaboration TA FD (Fluorescence detector) ELS: Electron Light Source TA-EUSO location located at Black Rock Mesa FD Station Electron Light Source at 100m Most nearby SD is at ~3.5 km Central Laser Facility ~21km

Panother step: Mini-EUSO Approved by the Italian Space Agency in the VUS-2 Call (ranked 9 out of 70)-Included by Roscosmos in its program

Mini-EUSO: Science objectives a.1) UV emissions from night-Earth 6.5 km resolution, from 2.5 micros and above +-51° Noise from different lightning conditions, moon phases Noise from different inclinations a.2) Map of the Earth in UV a.3) Study of atmospheric phenomena a.4) Bioluminescence of Animal and vegetal a.5) Study of meteors and Search for Strange quark matter b.1) First use of Fresnel lenses in space b.2) Optimization of characteristics and performances of EUSO b.3) Raise the technological readiness level of the Hardware and test SiPM

Mini-EUSO (2) Delivery to Roscosmos end 2016 Mini-EUSO block scheme: a refractive optics based on two Fresnel lenses images UV light on 1 PDM (36 MAPMTs). A SiPM moule is an option. 10 cm 10 cm Delivery to Roscosmos end 2016

Status: Japan The Japanese consortium has applied in Spring 2014 to a call for small scale projects open by ISAS/JAXA for a Japanese MOO participation to the KLYPVE-EUSO mission  Approved by JAXA in July (2014) with the constrain that the funding/programmatic scenario must be clarified by December 2014. Intense studies between RIKEN (on behalf of the JEM-EUSO collaboration) and Moscow State University (MSU, Russia) to develop a K-EUSO concept. JEM-EUSO is in standby, not dead…. Too severe constrains on mass budget in the last call issued by JAXA/ISS in Spring 2014, but still efforts in the US and in EU countries

Russia The KLYPVE mission is studied by MSU and Energia: it is a program of ROSCOSMOS. Phase B should start soon. Limits of the old KLYPVE design Intense efforts toward a K-EUSO joint mission. However constrains from the Russian side (keep mirror optics instead of refractive lenses…) Recently (September 2014) a joint protocol between MSU and RIKEN has been signed.

An essential milestone reached in 2013 US and NASA An essential milestone reached in 2013 The NASA Science Mission Directorate approved the JEM-EUSO APRA proposal submitted by the US-EUSO team led by Angela Olinto (Chicago University). Funds are now flowing in the US and support EUSO-Balloon activities. JEM-EUSO is a mission recognized by NASA This might be the starting point for a stronger involvement of NASA in the mission aspects (launcher, mass, integration …)  next step? An MOO in the open call? Proposal for a Balloon?

* ELIPS European Life and Physical Sciences in Space Programme ESA EUSO is a study included in the ELIPS program of ESA’s Human Spaceflight and Exploration Directorate (includes ISS activities). An International Topical Team on “JEM-EUSO” has been established by ESA. It has been recently renewed. ESA has always be willing to act toward a coordinated plan among the international agencies and continues to support the developments for an EUSO-like mission and sees positively the collaboration with Russia * ELIPS European Life and Physical Sciences in Space Programme

Second strong suggestion: stay on the ISS ESA (2) Clear suggestion: keep the mission profile at the level of an EUSO-like mission, do not give up with the science requirements! Second strong suggestion: stay on the ISS Renewed support to the EUSO-Topical team…

ESA Topical Team on “JEM-EUSO” Program to support the activities to develop JEM-EUSO: our policy has been to support travelling Students and postdocs from the participating countries (mainly Europeans “at large”) and the participation of “seniors” to key meetings. First tranche completed. Very effective use of the funds: 34 missions supported (20 kEuros)! A second tranche will be available for end 2014 and 2015.

Future? R&D: Operation in Utah of EUSO-TA (early 2015) Data Analysis  Second flight of the EUSO Balloon (in 2016) Operation of Mini-EUSO (delivery to ROSCOSMOS in 2016) Toward K-EUSO: Reach a final configuration of the mission (December 2014) Define the international role sharing Define a realistic development plan (to completion) Toward an EUSO-like mission: A team will develop a concept and then a proposal to be submitted in M5 (Simulation and Science WGs must play a key role) Explore all possibilities in the US.

Clarifications The new list of the JEM-EUSO members has been approved the last June in the Collaboration meeting in Palermo. The web site will be updated soon. The delay was caused by the late arrival of requests of modification. The list of authors does not coincide with the list of members. It includes members that have left the JEM-EUSO collaboration and will stay in the authorship until June 2015 Authors who have left the JEM-EUSO collaboration have not the right to access new data (e.g. the EUSO-Balloon data). New members will appear as authors after six months. The Pis are requested to update the national list at each collaboration meeting. Not at any time.
