The workshop will take place in London (UCL) on 7th November 2012.

We remind you that registration to the workshop is open and free of charge.

However, the number of places is limited to 30 and bookings will be accepted on a first-come, first-served basis.

Also please see more new examples on plasma chemistry page, the library is constantly growing.

Look forward to hearing from you and seeing you at our workshop!

The Align feature allows you to calculate cross-sections for a molecule oriented in a particular way, rather than as an average of all orientations. This feature can be useful for example when working with laser aligned gases or liquids or thin film coating of a substance with aligned molecules.
The outputs can show how the double differential cross sections change as a function of both molecular alignment, and also as a function of energy. See the demo for the water molecule here

As a reminder, below is a list of other cross-sections which Quantemol-N can calculate:

• Elastic cross-sections
• Electronic excitation cross-sections (extended to high energies) Super-Elastic cross-sections between excited states
• Electron impact dissociation
• Scattering reaction rate
• Resonance parameters
• Ionization cross-sections
• Dissociative electron attachment
• Atomic cross-sections
• Differential cross-sections
• Momentum transfer cross-sections
• Liquid state approximation (cutting off the long range interactions)

Please feel free to contact us and arrange a web-demo of the software.

You can also meet us at conferences in 2012 announced at our web-site diary

We are glad to announce our next Quantemol Workshop, which will take place on the 7th November 2012. Among speakers are academic and industrial researchers from Intel, Infineon, Eindhoven Universiy and LSPM, Paris. Please see this link for more details.

Thank you very much to those who have attended the talk of Prof. Tennyson on 17th January at “8th EU-Japan Joint Symposium on Plasma Processing” in Nara (Japan). For Prof. Tennyson it was a great pleasure to visit Japan and get to know many scientists in Asia working in the field of plasma physics. We are looking forward to the Symposium in Slovenia next year!

You can find the presentation slides of the talk following this link:“Calculated low-energy electron-molecule collisions for plasma problems” Jonathan Tennyson, UCL, Japan 2012

This year we have issued an updated brochure for Quantemol products and services. Please visit this link to upload it Brochure 2012. Your comments and questions are very welcome.
Also we are wishing you a Happy New year of Dragon!

Best regards,

May this Christmas end the present year on a cheerful note and make way for a fresh and bright new year.
We wish you a Merry Christmas and a Happy New year!

These are a few of this year’s achievements which we are proud of:

- Quantemol has successfully released Quantemol-D, a user friendly Java interface making HPEM plasma codes more accessible for non-specialised users.

- Quantemol-N was updated to versions 3.8 and 4.0 and 4.1, which now include momentum transfer cross-sections calculations and many other useful features!

- Quantemol held its first workshop in June, “Linking simulation and experiment”. It was a very congenial event, gathering people from academia and industry. We are planning to organise another workshop next year, with more actual topics and interesting training sessions. We’ll be in touch!

- Quantemol also participated in the following events: TPW, IOP PPC, 38th EPS, ISPC-20, ICPEAC, ICPIG, SCD, AVS, DPS, GEC.
Next closest events where you can meet us next month are The 9th Technological Plasma Workshop in Manchester and The 8th EU-Japan Plasma Processing Symposium

- Most recent news is a joint publication with Tokyo Electron Ltd, in Solid State Technology’s electronic version “Predicting plasma in wafer etch and deposition via quantum mechanics”

We hope that the next year will also be fruitful and that we will deliver even more to fulfil your research and development needs and interests.

Best wishes and regards,

Quantemol Team

We hope you will find it interesting to read.

Also I would like to remind you that you can meet with Prof. Tennyson:

- next week at GEC conference where he is giving invited talk in Electron-molecule collisions section
- in January next year at 8th EU-Japan Joint Symposium on Plasma Processing with special emphasis on Atomic and Molecular Database for plasma and surfaces (16-18 Jan 2012)

We are looking forward to seeing you at these events.

Examples

For those who could not make it to our workshop in June this year, please have a look at the video recordings of the talks which were presented.
Of course, these are the shortened versions of the talks and we encourage you to attend our workshop next year and enjoy full talks, discussions and meeting with colleagues.

I hope this was of interest to you and we are looking forward to seeing you soon.

It will be distributed among current customers using our support service.
New features of Quantemol-N 4.0 include:

• Momentum transfer cross-section calculations;
• Updated R-matrix codes including parallel scatci (which significantly reduce calculation times on multicore machines).

Also please bear in mind the recent development of a dissociative attachment cross-sections estimator (a new method in Quantemol-N, which does not appear in the R-matrix codes).

Recently calculations have been run on Cl2 using Quantemol-N’s dissociative electron attachment estimator, and the resulting cross-sections are in excellent agreement with numerous published values, across a variety of scattering energies. These results were presented by Prof. Tennyson at ICPEAC 2011, Belfast, 28 July 2011: “PR: Electron and positron molecule collisions using the R-matrix with pseudostates method,” Jonathan Tennyson.

We have successfully run Quantemol-N to calculate electron collisions with atomic oxygen, reproducing several known excited states in good agreement with experimental data, and from these super-elastic cross-sections have been produced to match the experimental literature. This is significant as oxygen has a non-standard triplet-P (3P) ground state whose correct electronic configuration can be difficult to obtain.

Please find below presentation slides, which has been used at the workshop.
