  1. Dr. Stefan Stahl, CEO Company Introduction and perspectives for a PhD student / ESR Precision Electronics for Science and Research

  2. First Projects: Design of Precision Ions Traps for Fundamental Research See our Publication Contributions: Eur. Phys. J. D 22, (2003), 163 Phys. Rev. Lett 92, 093002 (2004) J. Phys. B: At. Mol. Opt. Phys. 38 (2005) 297–304 Who are we? • Founded in 2002, • Spin-Off of Univ. Mainz • Main 2 Company goals: • knowhow for scientific groups • being related to ion trapping/detection • provide tailored custom-made electronics • for Beam Lines, Atom / Ion Traps and other science fields

  3. Highly successful collaborations 2004-2016 with • Max-Planck Inst. Heidelberg- CERN (Switzerland) - KBSI (Korea) • GSI (Germany)- London Imperial College- Riken (Japan)... others • (industrial, non-disclosed) Collborations • Achieved Goals: • Quantum State detection • of single particles • - high resolutionSingle Ion detection

  4. Key aspects • Deep Cryogenic Setup • Quantum Bits consist of • Spin and Cyclotron degree • of Freedom • Planar trap structure allows • for easy Scalability 200mK Resonator for Motional and Spin detection Planar Trap Designs milliKelvin Amplifier 2015-2017 Quantum Computation Setups Our Company provides leading contribution to a Multielectron Qubit trap (2005 to 2011) QUELE-Project, EU funding FP6-003772 see also our publications Eur. Phys. J. D 32, 139–146 (2005), Eur. Phys. J. D, 50:97–102 (2008)

  5. Customized FT-ICR Setup: KATRIN experiment 2003-2017 development of trap and detection system

  6. Stahl-Electronics Products • Ultra precision voltage/current sources • for most precise experiments • Cryogenic detection electronics

  7. Precision DC-Voltage Supplies for Ions (Ion Traps, Ion Guides, Steering electrodes) UM 1-14: multichannel precision supply Stability at 10-8 level +/-14V range HV series multichannel precision supply Stability at 10-6 level +/-50 to +/-1000V range

  8. UM 1-14: multichannel precision supply with +/-3V to +/-14V range For most precise experiments:Ultra High Quality Voltage Source UM 1-14 10-8 Grade Stability (0.03ppm rms at 10V) Quantum Spin State detection using our voltage supply UM 1-14: e.g. Eur. Phys. J. Special Topics 224, 3055–3108 (2015) DOI: 10.1140/epjst/e2015-02607-4

  11. Cryogenic Preamplifiers: 4.2K Gallium-Arsenide-based (GaAs) - ultra low noise image charge amplifiers - with single particle sensitivity NexGen3-Preamplifiers „FT-ICR-Octagon“ for Precision FT-ICR Quantum State and Spin detection • State-of-the-Art Sensitivity (un at 0.35nV/rt Hz) • for non-destructive image charge detection • detects motional trapped charges (no Lasers required)

  12. Latest Projects Time Being (2017):- Collaboration with GSI groups (Germany) - US-groups (MSU, Michigan, Harvard)- Base Collaboration (CERN, Switzerland)- Space Agencies (Space Electronics)New Cryo Projects:- 200mK to 4K amplifiers for QPCs, STM (TU Ilmenau)- ‚Super Sensitive‘ charge detection transistors 2015: first ‚own‘ cryo-FET

  13. Perspectives for a ESR / PhD student Background: Ground breaking ‚Super Sensitive‘ charge detection transistors developed by the LPN/France Appl. Phys. Lett. 105, 13504 (2014) Collaboration Stahl-Electronics with LPN since 2015 in favor of adaptation of this technology for image charge detection 3mm x 2mm First implementations during 2015 for FT-ICR and RF-Amplifiers

  14. Development Tasks for a PhD student • Systematic characterization of front-end transistors • identification of their weak points and strengths under various environmental conditions (magnetic field, temperature, heat loads) • hard- and software implementation into complete ready-to-use systems • System testing at real setups (e.g. Hilite/GSI, CERN) • New detector ideas ?

  15. ESR / PhD student education • The trainee will become an expert in cryogenic electronics and analog circuit design • learn to develop ‘fool-proof’, easy-to-use electronic systems • understand complex systems and break them down into simple handling rules • skills like giving talks, presenting data and teaching to other students will be developed.

  16. Networking and Secondments • Participation in AVA schools • Training weeks & conferences • Website publication of own activities, Videoblogs • Training in project management, definition of deliverables and milestones, • Frequent secondments to GSI facility, atomic physics group for practical experience and collaboration with single-particle precision experiments • Secondment to group of Prof. Blaum, MPI-K for information exchange of single particle detectors • Secondments to the CERN group • … and more…. ?
