description:
	In the last run, Ag island growth on Si(111) at low temperatures and annealing was studied at 3.8 ML coverage. Only one-height transition was seen. 2.2 ML coverage, which corresponds to the percolation transition coverage, should be investigated to see two-height transitions. Also coverages above 6 ML should be studied. For 6.4 ML coverage shows a tendency to form flat surfaces. Expected turn-around time for bake-out and outgassing is 32 hrs. Allocation of multiple 16-24 hrs slots separated at least 48 hrs will be welcome.
