Getting access

The access to the Support Labs: Microscopy infrastructure including AFM is granted primarily in conjunction with beamtime at MAX IV Laboratory. It is important that the users select SPM-lab as an additional beamline in DUO (see below) when submitting their proposals. The next proposal call opens 2022-09-05, will close on 2022-09-26 and covers beamtimes for the period Februari – August 2023 (See: https://www.maxiv.lu.se/users/proposal-calls/)

It is occasionally possible to perform short, unscheduled feasibility checks on unknown samples in order to support a future proposal.

Writing proposals

Most of the beamlines at MAX IV Laboratory are oversubscribed, so proposals should be compelling and carefully written in order to be chosen by the advisory committee. If access to the AFM lab is desired, the users must include a brief description of a planned AFM experiment. Users are always welcome to send the “AFM-part” of the proposal to the AFM staff if feedback is wanted.

We stick to a standard beamtime allocation at 1.5 GeV ring, where beamtime begins 0900 Wednesday and ends 0900 the following Monday. When writing proposals, request and plan the following 4 hours/shift, 6 shifts/day, 5 days.

Fast access and self-booking

There is a fast access proposal option available for getting a combined beamtime/AFM measurements. We are working on adding sole AFM measurement to fast access track, but as of today this option is not available yet.

We also are working hard on simplifying the access to the AFM instrument for those users in need of fast and somewhat simplistic sample morphology characterization. A self-service booking system for the AFM will be available soon for general users(requires a valid DUO account for logging in).

Regardless of the proposal situation, we encourage anyone with ideas for experiments to get in touch with Nikolay Vinogradov (lab manager for AFM).

Please, note, that the machine is placed in Optics Metrology Lab. The lab is a clean, restricted environment where general user admittance is only permitted after clean room training. Please, contact Louisa Pickworth regarding your lab access. This also means that you need to schedule your experiment with the operator(s) well in advance.

Remote access and operator’s help

As of today there is no remote access to the AFM instrument that can be granted to general users.

The users with experience in AFM may be granted the permission to run the instrument themselves after an introduction. Users who would require operator’s help in order to run their AFM experiments must get in touch with lab manager well in advance to discuss and agree upon the workflow.

Data policy

The AFM control PC is not connected to any network, therefore the user data will NEITHER be uploaded to the local MAX IV network, NOR made available online. You must bring a new – unused and unopened – USB memory stick for copying your data. Upon your request we may store the copy of your data locally on the control PC, depending on the data size.

The instrument

The microscope is Veeco/Digital Instruments (now Bruker) Dimension 3100.

It clears a field of view of max 90×90 micrometers with max 5 micrometer total height difference. The lateral resolution for 90 micrometer FOV is better than 50 nm, for 10 micrometer scan – better than 2 nm.

The sample size must be below 20 cm (8″) diameter and 2 cm height.

We provide cantilevers for user experiments, however, users are welcome to bring their own cantilevers for tapping or contact modes.
