- ... that in 1958 the Scyla theta pinch device was the first to demonstrate controlled nuclear fusion in the lab? Source: broms, bromberg and cleary all talk about this record

new enough, definitely long enough, interesting, cited, well-formed hook. My only tiny gripe would be could/should we call it a "laboratory" rather than a "lab" as this is, after all, an encyclopedia? The Rambling Man (Keep wearing the mask...) 15:59, 13 May 2022 (UTC)
Syllac or Scyllac
[edit]The article uses both Syllac and Scyllac (note the 'c'). Which is correct? Chris857 (talk) 05:02, 22 May 2022 (UTC)

I have a conflict of interest: I am one of the co-inventors of the spherical theta pinch, so I am requesting this addition rather than making it myself. The article currently covers only cylindrical, fusion-oriented theta pinches; I propose adding the following short section on the spherical variant, placed before "See also". All statements are referenced, including independent work (Xu et al., Institute of Modern Physics, CAS Lanzhou). I welcome any changes an uninvolved editor considers appropriate.
Spherical theta pinch
[edit]The spherical theta pinch (STP), originally also called the low-frequency inductively coupled plasma (LF ICP), is a non-cylindrical variant developed around 2008 at the Institute of Applied Physics, Goethe University Frankfurt, by Christian Teske and Joachim Jacoby.[1][2][3] Instead of a solenoid around a linear tube, a coil of a few windings is wound around a spherical glass discharge vessel, and a capacitor bank is discharged through it via a thyristor switch.[4] Energy transfer efficiencies of up to about 80% from the capacitor bank to the plasma have been reported, compared with roughly 59% for conventional small theta-pinch devices, which was attributed to improved transformer coupling between the primary circuit and the plasma.[5][2] Because no electrodes contact the plasma, the device was investigated as a long-lifetime plasma target, including as a heavy-ion plasma stripper at GSI Darmstadt for the FAIR project, and as a pulsed ion source.[6][7]
