Technical developments on: Vacuum Tubes; X-Ray
Equipment; Ultra High Voltage Equipment; Industrial X-Ray Techniques; Medical
X-Ray ... ; Siemens-reiniger-Werke A.G. Rudolfstadt and Erlangen; C.H.F. Müller
& Co hamburg; Rich.(ard?) Seifert & Co leipzig; Metallgussgesellschaft Leipzig;
Siemens Organisations; N.V. Philips Gloeilampenfabrieken Eindhoven, Holland;
german X-Ray Industry; The investigations started on 5 May 1945 and was
completed in Bad Oeyenhausen on June 30, 1945; Most Siemens tubes used beryllium
windows whereas Müller did not use beryllium windows in most of their
tubes that operated at less than 120 Kv.P. ... ; Accordingly Lindemann Glass
windows are used for diffraction ... ; Two diffraction tubes with titanium
targets were recently made by Siemens for Prof. Glocker, the German
'iron-expert" in the Kaiser Wilhelm Institute at Stuttgart .. ; To make chronium
targets, Siemens electroplates chromium to a thickness of 1 mm ... ; Siemens
used magnetic focussing on one of their diffraction tubes and obtained an
effective focal spot size of 1 mm square ... ; A 300 Kv.P. 1000 ampere (10-7
second) cold cathode tube was developed by Prof. Herz (Hertz?) of Siemens and
Halske in Berlin, and was used in the University of Nürnberg ... ; As a matter
of "vacuum tube interest" It was reported that Dr. Bowers left the Philips
(Eindhoven) organisation in 1939 or 1940 after a series of arguments with the
management over the Metalix tube design. ..... It is understood that after
the management won this argument, Dr. Bowers purchased a small optical company
in Delft; The unusually high voltage flexible cable construction permitted the
use of flexibility connected end ground tubes, heads at 200 Kv.P. and higher ..
; .... Work was being done by Zeiss at Jena .. ; In 1942 Siemens also started
production of a "new and improved Konvulsator" for administering electrical
shock treatment for schizophrenia, etc. .. ; Ultra High Voltage Equipment ...
C.H.F. Müller ... 25 megavolt betatron about the first of this year (1945?) ...
; In December 1944 the M.V. Research Association completed the calculations and
layouts of a 200 megavolt betatron, to operate on 50 cycles ... This betatron
was to be constructed by Brown Boveri and Cie A.G. in Heidelberg ... It is
understood that Brown Boveri completed detailed construction drawings of this
betatron about the first of March of this year (= 1945) ; Two betatrons had
recently been constructed and were being tested at the Siemens-reiniger plant in
Erlangen .... Prof. Bierman (Biermann?) of A.E.G. in Berlin was reported to be
working on the design of a 20 megavolt betatron .. ; The Philips "cascade"
circuit was used for the neutron generators .. ; .... Curie Institute Paris .. ;
Curie Institute, Paris: "Largest cyclotron on the continent"'. Constructed under
supervision of Prof. Bothe during german occupation .. ; Russia: "Three or four
or more" cycloytron installations were reported to be in Russia .. ; Sources of
Supply: ... Tantalium, Siemens & Halske, berlin was the only producer of
tantalium in Europe. Note: All of the tantalium ore used in germany originally
came from Australia. About 1939 Dr. Kolligs of Siemens & Halske in Berlin
developed an economical method for refining tantalium from the large amount of
refuse that had been accumulated from the previously used refining process.
Because of this there was no shortage of tantalium in germany; Columbium
(niobium) was also recovered as a by-product from the refuse tantalium ... ;
Beryllium: Heraeus Vacuum Schmelze hanau Also Degussa Frankfurt .. Note Heraeus
was owned by Siemens .. Degussa supplied berylium to Müller; Tungsten (=Wolfram)
Osram berlin Also Deutsche Edelstahl Werke Berlin, factory in Reuthe Tyrol .. ;
Molydenum same above; Glass Schott & genossen Jena .. Also Glaswerk Fischer
Ilmenau: Also Glasfabrik Weisswasser G.m.b.H. (Owned by Philips); Transformer

Kabelwerk, Gartenfeld bei Siemensstadt berlin .. ; Special High resistance Wire
Dr. Schildbach Rheinische Feinstahrindustrie (Feinstdrahtindustrie?, AOB);
Special Paint I.G. Farben Frankfurt .. ; Siemens-Reinigerwerke .. Dr. Wölfel
Chief Director .. dr. Albert Zimmer Head of Physical research Lab and X-Ray Tube
Development .. ; Dr. Werner Jacoby Note Dr. jacoby was recently evacuated from
Vienna, where he was in charge of research and development for all Siemens &
Halske vacuum tubes except X-Ray ... ; The following figures will indicate the
monthly production of this plant as of March of this year (= 1945) ...
