The Experimental Solid State Physics group operates a 50m2 cleanroom located in the Blackett building. It is a class 1000 environnement, meaning that less than a thousand 0.5 micron particles can be found per cubic foot. It is used in semiconductor, polymer and nanotechnology processing, and welcomes more than 50 users, EXSS research staff, as well as MSci students and external visitors.


The cleanroom is managed by the cleanroom committee:

Cleanroom PI: 
  Alasdair Campbell
Cleanroom Manager:  David Mack


Cleanroom landline:  0207-594-7707

Please do not hesitate to contact any of us for further information concerning the cleanroom, or to report incidents/accidents/safety issues within the cleanroom. 

How to obtain cleanroom access?

In order to register for cleanroom access, please contact directly David Mack. You will need to attend an iduction with the cleanroom manager David Mack, fill out a registration form, a risk assessment form, a COSHH form, follow a safety lecture, and be assigned a 'cleanroom mentor'.

Short term visitors and undergraduate students are allowed access to the cleanroom provided they are accompanied by a cleanroom user who is a member of staff, or a Postdoctoral Researcher (NOT a student). Please contact the cleanroom manager in time for a proper induction briefing (David Mack).

Safety in the cleanroom

The cleanroom is for the sole purpose of performing semiconductor, polymer and nanotechnology processing. The work quality and safety of everybody depends on how well each user has understood the safety issues present in the cleanroom.

All cleanroom users must therefore have followed a "Safety Lecture" before entering the cleanroom. Should a large enough group of new users require an earlier lecture, please contact directly Alasdair Campbell or David Mack

You can also flip at any time through the on-line version: Cleanroom Safety Lecture_May 2016 and
COSHH for cleanroom users.

If someone needs to work over the weekends, Bank holidays and College holiday closures in the cleanroom; they must be a senior user and provide an Extended hours access form signed by the supervisor to David Mack or Stephen Cussell.

Keeping the cleanroom clean

Because getting work done implies working in a clean environment, a cleaning rota has been set-up to have 2 people responsible each week for the maintenance of the cleanroom.

Equipment & common procedures manuals

A general Code of Practice has been elaborated by and for cleanroom users. It contains useful information regarding general usage rules of the cleanroom, detailed safety procedures, descriptions of the most common cleanroom procedures, and a lot of common chemicals found in the cleanroom.
Please make sure you and your visitors have read through it: Code of Practice

The cleanroom equipment reflects the versatility of the research done in the EXSS group, ranging from the fabrication of nanosized ma gnets to organic solar cell processing.

Each piece of equipment has been assigned a steward who redacted a general user manual that you can download below:
