We regard gender equality and diversity as a strength and an asset.

Your team
You will be working in the Accelerator Development group consisting of a wide variety of experts within the accelerator field, including accelerator physicists, RF experts and laser experts. The Accelerator Development team is a part of MAX IV Accelerator Division, which is responsible for developing and operating all accelerator-based light sources at MAX IV.

Would you like to work at one of the brightest lightsources in the world?

MAX IV is looking for a Post Doc who will work on a longitudinal injection scheme for the MAX 4U project.

The accelerators at the MAX IV facility are the core components for production of synchrotron radiation. There are two storage rings and one linear accelerator. The largest of these accelerators is the 3 Ge V electron storage ring, which is the first in the world to employ a multi-bend-achromat magnet lattice to deliver ultrahigh-brightness synchrotron radiation. It is the first of the new generation of storage rings with extremely low emittance, of which only three are currently in operation, while several synchrotron radiation facilities worldwide are upgrading in this direction. We intend to stay at the forefront and are therefore already studying improved accelerator designs and components.

In particular, since January 2024 MAX IV is engaged in the design of a major upgrade to its 3 Ge V ring, called MAX 4U. The upgrade aims at an outstanding improvement in light source performance to maintain MAXIV’s competitive edge beyond the end of this decade. As we push towards lower emittance, we face the consequence of a smaller dynamic aperture. This becomes an issue for off-axis injection, the current method at MAX IV.

We will therefore investigate the possibility of longitudinal injection, which we believe is feasible with the MAX IV's full energy linac and the option to use the photocathode gun for ring injection. There will also be a unique opportunity to test longitudinal injection into the current MAX IV storage ring.

Your main work tasks will be

• Simulations of linac and ring beam dynamics for longitudinal injection using tools such as Elegant, and Matlab Accelerator Toolbox
• Development of Photo Gun Injection
• Experimental verification of longitudinal injection in the MAX IV 3 Ge V ring
• Co-author the conceptual design report for MAX 4U
• Take part in operational efforts of the MAX IV accelerators

To be successful in this role you need to have the following qualifications

• Ph D in accelerator physics or equivalent
• In depth knowledge of accelerator physics
• Knowledge of electron tracking codes such as AT2 and elegant
• Programming skills e.g. python, MATLAB, C
• Fluent in written and spoken English

Below are seen as merits

• Experience with storage rings
• Experience with linear accelerators
• Experience of accelerator operations

As a person you are a team worker, self-driven and work well under pressure.

Eligibility
Appointment to the position of postdoc requires that the applicant has a Ph D or an international degree deemed equivalent to a Ph D, within the subject of the position, completed no more than three years before the application deadline. Under special circumstances the Ph D can have been completed previous to the aforementioned three years.

Further information
This is a full-time, fixed-term employment. A postdoctoral fellow is employed under a period
of at least two years and at most three years. The period of employment is determined in accordance with the agreement “Avtal om tidsbegränsad anställning som postdoktor-2022-02-01” (“Agreement on fixed-term employment as a post-doctoral fellow, 2022-02-01”)
