Significant progress has been made on the HT-7 superconducting tokamak rece
ntly. Repeatable plasma discharges for up to 10.7 s have been routinely obt
ained, which nearly reached the present limit of the PF system. LHCD experi
ments have been successfully carried out. A full LH wave current drive for
up to 3 s has been achieved. A quasi-steady-state H mode was observed with
a very high plasma density for LHCD. ICRF waves were used for wall conditio
ning, startup, and fast wave and ion Bernstein wave heating. A new RF condi
tioning technique is shown to be a very powerful means of conditioning futu
re large superconducting tokamaks. The physical design of HT-7U has been ne
arly finished. The engineering design and some R&D have started. A 2:3 mode
l of the TF coil and a 1:4 model of the central solenoid with a cable in co
nduit conductor cable have been finished. Testing of the coils will start s
oon. The engineering design is under way in accordance with the schedule.
