Kick-Off Meeting of the ErUM Pro Project "PtychoP04"

Tuesday 30 Sept 2025, 09:30 → 15:45 Europe/Berlin

Seminar Room of Building B (Bernsteinzimmer) (Max Born Institute)

Kick-off Meeting

Capillary-based Soft X-ray Ptychography for Ultimate 4D Spectro-Microscopy with Versatile Sample Environment

The project aims to create the first coherent, digital soft X-ray microscope with a versatile sample environment, thus enabling a broad user community to fully harness the potential of highly coherent fourth-generation synchrotrons. We will employ ptychography for user-friendliness, the beamline P04 at PETRA-III for the necessary coherence, and capillary-based optics to realize the required photon efficiency. Through studies in magnetism, we aim to showcase the practical advantages and applicability of this novel, digital, lensless technology.

 

The project PtychoP04 officially started in July 2025 and has received funding for three years. With this workshop, we want to kick off the work in this project and tighten the bonds between the project partners. The program will be published later.

 

The meeting will take place at the Max Born Institute (MBI) on Sept. 30, 2025 from 10.00 am until 04.00 pm. Participants may arrive in Berlin on Sept. 29. There are two hotels in Berlin Adlershof located in walking distance from the MBI:

Airport Hotel Berlin	Dorint Hotel Berlin-Adlershof

 

Please book your rooms as soon as possible. If you need assistance, don't hesitate to contact the organizers at MBI.

Public transport via S-Bahn to Adlershof is available from Berlin Central Station (S9) and Berlin Südkreuz (S45 or S46). The required ticket category is "Berlin AB". From BER airport, both S9 and S45 go directly to Adlershof and require a "Berlin BC" ticket.

Please register for the event if you want to attend the kick-off meeting. There are no registration fees.

09:30 → 10:00 Arrival at Max Born Institute and Coffee

We will meet in Building B of the MBI. Please use the key pad telephone when you arrive at the door. We will the open the door for you.
