School and High school reminiscence

(years 50)
A lot of fun with home made soapbox cars (after school) and funny drawings (during school).

My portable... hu!... transportable tape recorder

(1959)

I was 15 when I bought an almost professional magnetic tape-recorder. This was an affordable Fidélité 58 by Magnétic-France (Radiobois, 175 rue du temple, Paris 3e) with a lamp electronic (no transitors yet) but offering a pretty good sound quality.
I connected it to the radio set and, every morning before school, I used to switched it on to record the famous and very funny radio soap opera "Signé Furax". There was no programmable switch at that time and thus I recorded several hours of junk each day to get my 10' of fun.
With a weight of only (!!!) 25 kg it was considered as transportable and I did traveled a lot with it.

First experiments at the ILL

(1972)

No neutron diffractometer already commissioned at that time at the ILL, the only available instrument was LI5, a four-circle X-ray diffractometer Siemens AED.
It was driven by a DEC PDP8 computer and the data input was through punched tapes on a Teletype terminal. Since the core memory was only 4k of 12bit words, our colleague, Alain Barthélemy, had hard days tracking any empty word to implement extra assembly language instructions in this very tight space.
Together with Michel Thomas, we trained ourselves to new diffraction techniques that, later on, we introduced on single-crystal neutron-diffractometers such as D8, D9, D10, D15. We also fought a lot with a gas flow cryostat and concluded that we had to develop more reliable techniques for ILL diffractometers.

Building the neutron diffractometer D8 at the ILL

(1973)

D8 was a very high flux neutron 4-circle diffractometer now replaced by D19. It had a stout eulerian cradle and this make it possible no compromise low temperature experiments (Displex cryocooler) and high pressure experiments (gas pressure cell up to 0.5 Gpa).

Refilling the helium cryostat of D15

(1984)
D15 was a neutron normal-beam diffractometer build by Michel Thomas. It is now decommissioned.
It had also a 4-circle option with a stout eulerian cradle with offset phi circle. Michel and I we solved the blind region problem through Renninger rotations.

I am preparing the liquid helium transfer line.

Science festival in Grenoble

(1992)

Students agglutinated around a Macintosh, a big success indeed! They are discovering "Video_ILL_interactive" an early multimedia presentation of the ILL. An Hypercard™ engine was used to drive a set of Magic™ animations and several C and Pascal interactive simulations of neutron experiments (A.Filhol, Jean de Combret, Yves Baulac, Albert Wright).

My friends Jacques and Nénesse in my office

(1999)

Together we developped ABFfit (neutron powder diffraction data analysis), MacSurvival (survival analysis for physicians), ABCstat (statistical analysis), three programs for Mac OS classical with advanced statistical algorithms.

ILL scale model

Modernization of the ILL scale model. Brieuc Segalen (http://briq.com) shows an early version of the new interface developed together with Olivier Vinot and Francis Gorgé.

My first smartphone/tablet application

(2012)

Neutrons4Science (for iOS and for Android) is an application developed together with Ipter. It offers a set a scientific animations demonstrating some aspects of neutron science and techniques. The animations are both 3D and interactive and one of them is in the form of a serious game.
