     In a draft paper, REBCO wiring has been reported to produce magnetic fields over 35 Tesla; the ARC design only needs 20T fields.

Usage notes

• The SI brochure (Sec 5.3) notes that [u]nit names are normally printed in upright type and they are treated like ordinary nouns. This includes the normal rules of plural formation.
• The NIST Guide for the Use of SI (Sec. 9.2) states: Plural unit names are used when they are required by the rules of English grammar. They are normally formed regularly, for example, “henries” is the plural of henry. According to Ref. [6], the following plurals are irregular: Singular —lux, hertz, siemens; Plural —lux, hertz, siemens. (See also Sec. 9.7.) There is no special exception for tesla.
• The zero-plural tesla is frequently found in scientific and lay literature.
