- DESY continues sanction measures against all Russian organizations: suspension of all collaborationis with research institutions: projects, publications, conferences
- guesthouses have been made available to Ukrainian refugees, usually around 30 persons
- cooperation with Kharkiv Institute of Physics and Technology #KIPT
- funding by @helmholtz for refugee scientists (~15 @DESY)

Severe resource bottlenecks 2023+

- 220 GWh energy supply,
- 100 GWh for accelerators, 90 GWh for XFEL LINAC
- Helmium: 60,000 m³/year
- Nitrogen: 9,000 t/year
- Neon extreme shortage
- 1% of inflation above 2% means the lab looses 2M€

- we have to rescue the car industry, the … industry, the … industry, people should not freeze at home
- we are running into the danger that we are loosing the next generation of scientists and engineers

Edgar Weckert: Overview DESY Photon Science
- inauguration of HESEB at SESAME
- strategy from 2018 until 2030: “you have to make adjustments”
- establishment of photon science scientific computing group at DESY
- (rushing through many highlights)
- thanks to all staff and beamline people doing the extra work in covid times

- Price increase in liquid Helium (needed for ultra-cold experiments): “maybe we have to make hot experiments.”

What about … liquid Tungsten?

Christian Schroer: PETRA III

New instruments coming up ~ next year:

- HIKA – Hierarchical Imaging #Karlsruhe station @ P23: systematic studies of small animals, e.g. insects, #invivo #imaging to start Q2/2024
- Applied Bio-Medical Imaging, Powder Diffraction and Innovation @ P25: joint ITT-FS project (industry, technology transfer)
- P63: OperandoCat, combined XAS/XRD/SAXS of operando studies of energy materials

PETRA III: one of the core facilities at DESY
- 6500hr/year operation,
- thousands of users

PETRA IV:
- diffraction-limited ~ 1 Â

#Synchrotron radiation: a swiss army knife for #science
- #energy
- transport & #technology
- materials for #quantum information
- earth & #environment
- #life & #health

human #health: from #drug development to its effect in the body

drug development -> drug delivery -> effect on tissue

Feature of PETRA IV: going from the smallest scale to the largest scale in one facility

Show threadMarkus OsterhoffJan 27, 2023

Needed for PETRA IV storage ring:
~ 4000 magnets, power supplies
~ 1000 vacuum chambers
~ 1000 pumps
~ 2500 racks
~ 48 RF cavities

DESY IV Booster: needs to be rebuilt; lattice is frozen, design progressing

New access scheme without proposal deadlines; instead:
- continous reviews,
- continous scheduling;
- average waiting time down to 20 days, not several months.
