Sven Tougaard has announced he's making his QUASES software available free of charge. This is a very generous action and XPS users around the world will thank him for his kind offer. www.linkedin.com/feed/update/...

Important Announcement

The QUASES-Tougaard software package, widely used for XPS inelastic
background analysis and for determining the composition and morphology of
nanostructures, will become available free of charge beginning September 1,
2026.

From September 1, 2026
. Free for personal, educational, and academic use
. Commercial use will require a separate commercial license

From January 1, 2028
. The software will become completely free for both non-commercial and
commercial use

Information on software download, installation procedures, and licensing
terms will be published on this page, on the official QUASES website
(QUASES.com), and on the QUASES tutorial video site:
https://zenodo.org/records/5499741

Background to This Decision
I have decided to make this change to ensure the long-term availability and
broad dissemination of the software throughout the global XPS community.

Although I remain in excellent health, at the age of 75 it is prudent to plan for
a future time- possibly a decade or more from now-when continued
distribution through my company may no longer be feasible. Over the past
several years, I have carefully considered various options and have
concluded that this phased transition represents the most effective and
beneficial solution for the worldwide XPS community.

I would like to express my sincere gratitude to the many hundreds of
research groups at universities, national laboratories, and commercial
organizations that have supported the continued development of QUASES-
Tougaard through the purchase of software licenses over the past 32 years.

With the improvements implemented in recent years, Version 7.51 has
reached a mature, stable, and robust state. Consequently, the need for
future modifications is expected to be minimal.

It is my hope that QUASES-Tougaard will continue to serve as a valuable
tool for researchers around the world for many years to come.

Off to AVS-71 for a fun week of science. Leaving rainy Manchester behind for the 30C of Charlotte, North Carolina. Tough decision!

Last decent cup of tea before setting off to the North American SIMS Workshop in Northridge, LA. Looking forward to catching up with old friends and making new ones.

... and that's a wrap! Last flight of the year (AFAIK!) at dawn over Amsterdam. Greece, France, Belgium, Brazil and South Korea in 2024. Looking forward to some time at home, if I can remember where that is!

Any minute now... Just about to give my invited talk at the Practical Surface Analysis 2024 conference in Busan, South Korea. Wish me luck! fairspectra.net #PSA_24

Title slide for presentation. Title reads "Towards a common file format for hyperspectral images"
